Summary of the Tradesports DEMS.HOUSE.OVER29.5 issue, and the TS “credibility gap”

Alex Forshaw November 20th, 2006

In the past weeks, there was something of a dust-up over TS’ handling of the DEMS.HOUSE.OVER29.5 contract. According to all American media, the Democrats needed 15 new House seats to gain control of the House of Representatives. And, indeed, in the final days leading up to the election, there an excellent synchronization between the DEMS.HOUSE.OVER14.5 contract and the inverse of HOUSE.GOP.2006, indicating a perceived equivalence between 100 - p(HOUSE.GOP.2006) and DEMS.HOUSE.OVER14.5. Thus, the (presumably overwhelmingly American) market inferred that TS would follow the same convention as all American media, mainstream and otherwise, did. And according to American media, a Democrat replacing independent Socialist Bernie Sanders didn’t count as a Democratic pickup, because he already caucused with the Democrats anyway. However, TS initially disagreed with that, and counted Sanders as a non-Democrat. (More on that soon.)

Speaking personally, TS reinforced this perception–that independents who caucused with the Democrats counted as Democratic seats, and if they were replaced by an official Democrat, that wouldn’t increase the Democrats’ vote total–by specifically stating, in regards to SENATE.GOP.2006, that a “loss” of the Connecticut seat to Joe Lieberman (who had switched from Democrat to Independent) would still be counted as a Democratic seat, because Lieberman already caucused with the Democrats anyway.

The fine print of the Tradesports DEMS.HOUSE.OVERXX contracts was, for most of the time, fairly clear in stating that the Democrats started from 201 seats, and anything over that number would constitute a gain. Judging from the activity of DEMS.HOUSE.OVER14.5, however, I believe that most of the market inferred (as did I) that 201 was the initial starting number of of Democrat seats according to American convention as well as TS, and didn’t realize the difference between the two systems. A very technical mistake, but not one for which TS deserved blame.

However, TS threw a monkey wrench in the system by telling forummer “gekko6″ that Bernie Sanders’ Independent seat going Democratic would not count as a Democratic pickup, because Sanders had already caucused with the Democrats in the first place. In this decision, as in its Connecticut Senate decision, TS showed an impressive grasp of the vagaries of the American political system–namely, that the size of each caucus was the real issue; and Congressional majorities being determined on the basis of caucus, not party affiliation, it only made sense to calculate the shift in power in the House on the same basis.

Unfortunately, that also meant that TS had, at the same time, repudiated its own convention for what constituted a “gain.” “gekko6″ had already been very aware of this issue, because he had pointed out that the actual starting count according to the American system was 203, not 201–due to Sanders’ being an independent endorsed and unopposed by the Democrats, and the vacancy of Bob Menendez’s seat after Menendez was appointed to the Senate by NJ Gov. Corzine. (From a foreign, technical perspective, this was defensible–Menendez’s seat was vacant, so the winner on Nov. 7 would count it as a “gain.” However, the Republicans did not contest Menendez’s very Democratic seat, so in the American convention, it was never counted as a Democratic pickup.) Tradesports’ convention effectively said that the Democrats gained two more seats than the American convention did, and several days after the November elections, the American convention said that the Democrats had gained 28 House seats with 1 certain to go Democratic in a runoff (in Louisiana), so 29 seats total, while the Democrats had effectively gained 31 seats according to TS. Hence the problem with DEMS.HOUSE.OVER29.5. And while a legalistic interpretation would favor TS, I believe that the synchronization of DEMS.HOUSE.OVER14.5 and 100 - p(HOUSE.GOP.2006) indicated that most trading during the final few days showed that the market was unaware of TS’ own convention for the election outcome.

I sent Tradesports an e-mail about it (apparently they don’t accept new entrants to their forum anymore, because my application has been pending for about a month), and they replied that the new number of Democrats minus 201 would constitute the number of Democrat gains, thus contradicting what they had told “gekko6.” I then publicly denounced TS for waffling the issue. TS did nothing, and apparently hoped the controversy would blow over. A bunch of recounts in close races later, TS appears to have lucked out, because according to the American convention, the Democrats now have at least 233 House members, up from 202-plus-one-Socialist, so the American system now says the Democrats have gained 30 seats and DEMS.HOUSE.OVER29.5 has been fulfilled either way.

Honestly, I was impressed that TS understood the American system as well as they did. Unfortunately, TS’ subsequent “flip-flopping” showed that it did not, in fact, understand its own contract specifics. It also fit a larger pattern of cavalier disdain for its clients, often interpreting an ambiguous outcome significantly contrary to that of the market-majority (Harriet Miers confirmation, NK missile test contract) without appropriate compensation, setting up a joke “Arbitration Committee” that, if it even exists, has done nothing except infuriate customers, and most recently expiring sports contracts before the games were even concluded –and coincidentally raking in tons of expiry fees from people who weren’t given a chance to liquidate.

The latter, in fact, has happened with enough cavalier consistency that one can only wonder whether TS simply plans on milking its American consumers for as much as possible before closing the site to new American participants as a result of the recent US legislation. SportsBook has downgraded Tradesports to a C+ rating, which is at the very low end of what SportsBook can vouch for.

If TS plans on more effectively structuring its futures contracts, it should structure them along the lines of, “At 11:59:59 PM GMT on dd/mm/yyyy, Democrats will control ON or OVER XXX seats in the US House of Representatives.” If it wants to undertake a broader effort to restore its own credibility, it needs to stop the caprice that is fast becoming the norm for how it adjudicates contract outcomes–whether that adjudication occurs before or after the outcome has actually occurred. [added:] TS’ infrastructure and trader base are both excellent, and there’s no point in wasting those assets on sloppy legalese and interpretation.

Addendum: As for 100 - p (HOUSE.GOP.2006) vs DEMS.HOUSE.OVER14.5, I remember them consistently mirroring one another, and thinking to myself, “Aha! Efficient markets at work.” However, what little historical data TS makes publicly available makes it hard to judge that, and there were snapshots when the two were de-coupled, so perhaps a minority of perceptive traders _did_ trade on the differences in the rules. But in the sample of snapshots that I looked at, the two were coupled (within 2 points) much more often than not during the final days, when liquidity was high enough to make arbitraging the two contracts a worthwhile use of capital.

TradeSports-InTrade: United Nations > John Bolton as US Ambassador to United Nations - REDUX

I’ve spotted an interesting comment from Canadian trader Sacha Peter on the TradeSports forum:

This will be an interesting contract. Essentially, will Bush recess appoint him? I can’t see him getting past the senate confirmation process.

I lost a few bucks (literally, it wasn’t huge) in the previous confirmation debacle, so the way they worded this contract is very unambiguous and Tradesports appears to have learned one lesson.

So here’s the contract statement:

This contract will expire at 100 if John Bolton is the US Ambassador to the United Nations at 11:59:59pm on the date specified in the contract.

This includes (but is not limited to) confirmation by the US Senate or a recess appointment by the President.

The contract will expire at 0 if John Bolton is not the US Ambassador to the United Nations at 11:59:59pm on the date specified in the contract.

This includes (but is not limited to) withdrawal of the nomination by the President, withdrawal by John Bolton himself, failure to be confirmed by the US Senate or appoinment to an “acting UN Ambassador” role under the Vancacies Reform Act.

Due to the nature of this contract please also see Contract Rule 1.9 Unforeseen Circumstances.

The Exchange reserves the right to invoke Contract Rule 1.8 (Time Protection) if deemed appropriate.

This entry is a follow-up on my previous blog post.

PEAR lab (Princeton Engineering Anomalies Research) - REDUX - Retrocausality in physics

Chris F. Masse November 18th, 2006

In my previous blog post, I said that Princeton professor Robert Jahn has been unable of finding the right hypothesis about the so-called “psychic phenomena” (if any). I mentioned the work of a theoretical physicist, Olivier Costa de Beauregard, who interprets the E.P.R. paradox using the concept of “retrocausality” (the reversal of the arrow of time). I said that, speaking of the so-called “psychic ability” (if any), one could interpret the so-called “precognition” (if any) as a reversal of the psychological arrow of time, where the mind could receive information coming from its own future.

Well, today, via Jason Kottke, we have some news from the scientific world that scratches this concept of “retrocausality” (which we should not confuse with “finality”, I was told), and which seems to comfort the Costa de Beauregard’s interpretation:

Quantum theory describes the behavior of matter and energy at the atomic and subatomic levels, a level of reality where most of the more familiar Newtonian laws of physics (why planets spin, airplanes fly and baseballs curve) no longer apply. The problem with quantum theory, put simply, is that it’s really weird. Findings at the quantum level don’t fit well with either Newton’s or Einstein’s view of reality at the macro level, and attempts to explain quantum behavior often appear inherently contradictory. “There’s a whole zoo of quantum paradoxes out there,” Cramer said. “That’s part of the reason Einstein hated quantum mechanics.” One of the paradoxes of interest to Cramer is known as “entanglement.” It’s also known as the Einstein-Podolsky-Rosen paradox, named for the three scientists who described its apparent absurdity as an argument against quantum theory. Basically, the idea is that interacting, or entangled, subatomic particles such as two photons — the fundamental units of light — can affect each other no matter how far apart in time or space. “If you do a measurement on one, it has an immediate effect on the other even if they are separated by light years across the universe,” Cramer said. If one of the entangled photon’s trajectory tilts up, the other one, no matter how distant, will tilt down to compensate. Einstein ridiculed the idea as “spooky action at a distance.” Quantum mechanics must be wrong, the father of relativity contended, because that behavior requires some kind of “signal” passing between the two particles at a speed faster than light.

This is where going backward in time comes in. If the entanglement happens (and the experimental evidence, at this point, says it does), Cramer contends it implies retrocausality. Instead of cause and effect, the effect comes before the cause. The simplest, least paradoxical explanation for that, he says, is that some kind of signal or communication occurs between the two photons in reverse time. It’s all incredibly counterintuitive, Cramer acknowledged. But standard theoretical attempts to deal with entanglement have become a bit tortured, he said. As evidence supporting quantum theory has grown, theorists have tried to reconcile the paradox of entanglement by basically explaining away the possibility of the two particles somehow communicating. “The general conclusion has been that there isn’t really any signaling between the two locations,” he said. But Cramer said there is reason to question the common wisdom. Cramer’s approach to explaining entanglement is based on the proposition that particles at the quantum level can interact using signals that go both forward and backward in time. It has not been the most widely accepted idea. But new findings, especially a recent “entangled photon” experiment at the University of Innsbruck, Austria, testing conservation of momentum in photons, has provided Cramer with what he believes is reason for challenging what had been an untestable, standard assumption of quantum mechanics.

Parting Shot: If “psychological retrocausality” (”precognition”, actually) could be engineered one day, then we could make a killing on prediction markets. I could have sold short the SENATE.GOP.2006 contract at TradeSports, and made as much money as scientist David Pennock did (or so he claims —and I saw that some vendor also made this self-interested and undocumented claim).

Prediction Markets vs. Political Pundits - 2006 US Senate (GOP control + individual races)

Chris F. Masse November 15th, 2006

… More exactly TradeSports-InTrade and Iowa Electronic Markets VERSUS The McLaughlin Group (PBS).

Reason Magazine writes:

Weirdly, the McLaughlin Group, the fustiest of all the talking head shows, had one of the best records this cycle, with Eleanor Clift, Lawrence O’Donnell, and John McLaughlin all predicting Democratic takeover of the Senate and calling nearly all of the close races correctly. Still, that old line about stopped clocks comes to mind.

Reality Check:

Vo, vo, vo. Not so fast. The McLaughlin Group is made up of five members. Three of them predicted the Dems in the US Senate, and so (if I’m correct) the associated probability was 3/5 = 60%. It does not strike me as an unanimous consensus.

As for TradeSports, Professor Lance Fortnow wrote that all (NOT: “nearly all”) individual 2006 US Senate races were predicted correctly.

Parting Shot:

If the small-L and capital-L libertarians at Reason Magazine sides with the leftist bloggers and media in the anti-PM backlash, and if some from-day-one prediction market supporter goes amock, then the logical conclusion is: The Prediction Markets Have NOT Arrived Yet.

Don Luskin loves prediction markets but loves punditry better.

My Observation #1: Don Luskin laments on being so wrong on the Monday before Election Day 2006. And, as a repentance, a Don Luskin full of contrition posts a YouTube replay of his series of bad calls, for everyone to see.

My Observation #2: In this 5-minute CNBC segment, it seems to me (and if I’m wrong, tell me) that Don Luskin largely deviates from the message generated by pre-Election 2006 prediction markets at TradeSports-InTrade. It seems that Don Luskin did forecast a slim victory (if any) for the Dems at the US House.

My Observation #3: Don Luskin had told me that his firm (Trend Macrolytics) has integrated prediction markets —they use them as a standard tool in their toolkit for predicting financial markets.

My Take: A more complete “integration” would be for a political pundit to mirror exactly the market-generated predictions, just like a hunting dog follows the scent of a rabbit —that is, to rephrase for the media what both HOUSE.GOP.2006 and SENATE.GOP.2006 were saying. Over the long term, the prediction markets will be more accurate than the smartest political pundit.

More Information: Donald Luskin is the chief investment officer of Trend Macrolytics. He blogs politics at Poor & Stupid.

My Thank-You Note: Don gave me tons of suggestions for the setting up of this group blog, Midas Oracle (including advice regarding the blog name, by the way). Thank you very much, Don.

Leftist bloggers and media’s backlash at the prediction markets - REDUX

Chris F. Masse November 13th, 2006

The leftist bloggers and media are conducting a repeat of the Moscow Trials. They bring in all evidence required for conviction (SENATE.GOP.2006), but they conscientiously leave out everything that pleads for acquittal (HOUSE.GOP.2006 + the individual races).

Whatever happened to… The Wisdom of Crowds? - Prediction markets flunk the democracy test. - [SENATE.GOP.2006 at TradeSports-InTrade] - by The Register - 2006-11-11

[About TradeSports's SENATE.GOP.2006] This week however the people spoke - and the markets failed.

My Take:

Physicists tell us that the future can’t be predicted for sure because:

#1. We can’t model everything completely, yet.

#2. We can’t measure anything precisely (so as to feed the models).

#3. We can’t reverse our psychological arrow of time, so as to be informed by our own future mind. (Don’t pay any attention to that impostor who says he can.)

Thus, it’s totally absurd to expect the prediction markets to do what physics says cannot be done —predicting the future with 100% accuracy. Prediction markets should not aim at absolute accuracy (against the real-world outcome), but at relative accuracy (relative to comparable institutions’s predictions).

Jason Ruspini expressed a similar opinion, today. (See his fifth paragraph.)

Political Factor Analysis

Jason Ruspini November 13th, 2006

David Pennock, Lance Fortnow and others on Marginal Revolution and DailyKos explain the “failure” of prediction markets for Senate control as stemming from the assumption that state-level elections are independent events, an assumption that ignores national movements in sentiment. Is there a way to test this idea? If a general anti-Republican/pro-Democrat wave swept across the country, decreasing the independence of individual elections, it might be expected that those Republicans who best represented the party line would fare the worst compared to what prediction markets and polls projected.

Voting records such as those available at the Washington Post can serve as a simple proxy for how representative members are of their given party. A legislator will be “typical” if their votes nearly always correspond to their party line. Now do the electoral fortunes of legislators who are more typical in this sense in fact exhibit a higher “beta” to general sentiment shifts? If (possibly after trimming special cases) this did not appear to be the case in the last election — if prices were not worse in proportion to how typical the Republican candidate was, then the lack of independence explanation is suspect. In that case, no explanation should be required either, since after all, 70% != 100%.

This is only a first pass, as an issue-level factor analysis should be more enlightening than one that remains at the party-level. This would also allow us to take the challengers’ views into account when modeling individual races.

In terms of the “defense” of prediction markets, apparently it needs to be pointed out ad nauseum that the question is not about their absolute success, but their success relative to alternate tools. Empirical findings confirm the superiority of prediction markets to polls, and the logic of motivation is clearly in their favor. In terms of anecdotal evidence, consider these opinions submitted in response to a television survey on confidence in polls conducted on 11/5/06:

I tell the pollsters the exact opposite of what I’m planning to do. It’s none of their business anyway.
Carole, Columbus, OH

I don’t believe in polls. I keep a penny by the phone. ‘Heads I’m a Democrat, tails I’m a Republican.’ I like to keep them guessing.
Tom, Seattle, WA

Maybe polls should be more emotive and oblique, and ask questions like, “What issues anger you the most?” and “What issues most affect your day-to-day life?”. Prediction markets would then be able to digest this data and better gauge the independence of elections.

In any case, both political factor data and analysis techniques will see development before the 2008 elections. On the latter side, this will include working through ambiguities and accounting for correlations in issue preferences (which constrain party platform “optimization”).

Coming from a politics-obsessed family, we (family and I) have been fans of predicting election outcomes for as long as I can remember. We are all conservative-libertarians of one hue or another, and I began writing “wingnut” screeds in eighth grade for my junior-high newspaper. What with the Florida Bush recount and 9/11, a superpoliticized era had dawned. My first forecast was 2002, and I got all the Senate races right but for one. Uncanny, I thought. Then came 2004, and I nailed that one too. Really uncanny–but then again, every clock was right twice a day, and this being the high and higher tide of “my side,” my predictions didn’t seem so uncanny in retrospect.

Fast forward to October 2006, and I was a junior in college with a mediocre academic record in finance and Chinese. An election was gearing up. I wanted to put my forecasting ability to the test. I also realized that, by blogging the rationales for my trades, it could become a valuable tool in my quest for a summer internship/job, to represent a side of me that my GPA didn’t represent at all. Not exactly lacking confidence, I put $2500 where my mouth was, and soon afterwards plowed in another $1000. I shifted in and out of many positions, but the common denominator was (as I said on my own blog some days ago) that I believed the market was underestimating the intercorrelation between congressional races, and especially Senate races all over the country. In other words, I bet very heavily on the Democrats taking both houses.

Three or so weeks into my blog, I was getting scattered, but very positive feedback about my material. People in Tradesports threads began quoting it, and a major Tradesports speculator asked me for some further opinions regarding the direction of the 2008 US presidential nominations markets. (I told him not to do anything other than short Hillary, but to especially not short Barack Obama, until after the election, and I couldn’t have any “gut feeling” until I had gauged what a Dem election victory would mean.) So I knew my material was good, but I was still pretty surprised, not to mention ecstatic, when WSJ reporter Jim Browning contacted me for information about election prediction markets. So I happily gave him everything he asked, and the superb WSJ article was the result. (That’s the non-$$, Pittsburgh P-G version.) But as our conversations continued into election night, I begain to despair about my positions…

In Virginia, George Allen had about a 12,000-vote lead with about fifteen counties remaining to vote. I knew they were in the pro-Webb counties (Fairfax, Loudoun, Richmond City…) but those precincts ranged from barely better than even to 72-28 (Richmond). Webb would have required statistically….unlikely turnout and/or margins in order to win. A lot of people on DailyKos and other communities emotionally invested in a Webb victory, processing new updates literally seconds after they came, had given up on Webb. Harry Reid came on TV and his body language screamed, “I don’t think the Senate is in play anymore, even though I thought it was a couple of hours ago…but that was too much to ask, anyway.” Without Virginia, the calculations for the Democrats’ taking the Senate became very grim, very fast.

Final polls (which I had spent the previous weekend trashing) showed VA breaking for Webb, comporting well with my own intuition. As the returns came in, however, Allen seemed to have an insurmountable lead with about 96% of precints reported. I concluded that Allen would win re-election, barely. Michael Barone’s forecast to the contrary, I noticed that the remaining precincts to report were healthy-majority Democrat (about 60-40, 65-35), but I didn’t think that Webb would be able to cut Allen’s lead in half–well, maybe half, but not zero it out. (I learned only later that when Virginia says “precincts reporting,” it apparently does not include absentee ballots when it says that. Or it reported them before it started tallying up the actual votes from the voting booths on that day. Or something. But a bunch of absentee ballots flowed into Fairfax later that netted about 7k more votes for Webb.)
However, rewinding to that despairing moment, the Democratic machines in Richmond City, Fairfax and Loudoun had waited until all other precincts had reported before reporting. Now, I don’t know about Virginia, but I know that in Missouri, the urban Democratic machines in STL and KC have a certain notoriety (in some circles, anyway) of waiting until every other precint has reported, and then releasing surprisingly high results (that usually imply incredible voter turnout–certain STL precincts reporting 97%, 100+% turnout isn’t unheard of), magically pushing the Democratic candidate over the top by a fraction of a percentage point. (I don’t want to start a flame war here–I think American politics is a blood sport, both sides have their different ways of playing dirty, and this was just something I didn’t factor in.) And six to twelve months after the election, some low level Democrats get a year in jail for voting fraud. It happens like clockwork, except that this time around I don’t think the MO Dems will need to resort to that. But I digress…

So I figured VA was lost when it wasn’t, and I puked up all the SENATE.GOP shorts. At one point, over 50% of my entire principal was gone. Then, after despairing for about ten minutes, I went back to the TS markets intending to try and make back what I could. Then I realized that Webb had magically jumped into a 2200 vote lead in VA with 100% of precincts counted. I had already looked at the counties and their turnout/margin statistics and figured that couldn’t have happened, but it had. So after losing over a couple grand…not to mention feeling like a complete idiot for throwing away $8000 by buckling at the last possible second, I hopped back on the SENATE.GOP train and rode it down to zero, and made back that entire original investment, plus about $150 left over.

So a lot of lost hair, Wheat Thins, NoDoz, bad grades and exhaustive political analysis later, I felt pretty vindicated, even though I had managed to squander 90% of the potential compensation. (I did indeed lose hair.) I had staked 1,000 shorts against SENATE.GOP.2006, well against the majority view of the market. As I recall, total volume going into the election was 35k or 40k trades, but because some significant fraction of that was the same positions being flipped back and forth between a stagnant pool of traders before I’d arrived, it was probably closer to 5% of outstanding positions. If my money hadn’t buttressed the market-minority’s view, the price would have been even more inaccurate–before election day, the price hovered around 70 percent, and without my heavy position on the “minority” side, it would have been closer to 80-20 in favor of the GOP holding onto the Senate. Plus, going into the election, I had stuck by my calculations even as the market had continued to erode my investment. Having that kind of confidence and analytical precision vindicated meant much more to me than $8-9000 in potential winnings lost.

Psstt… TradeSports traders… Wanna be rich?… Do like David Pennock: Get a PhD… with a major in probabilities

Although TradeSports’s individual state predictions and overall Senate prediction were entirely consistent, one might argue that traders underestimated the degree of dependence (correlation) among states’ elections. In fact, I made a few bucks selling the “GOP Senate control” contract on TradeSports using exactly that reasoning. The truth is, I probably just got lucky, and it’s nearly impossible to say whether TradeSports underestimated or overestimated much of anything based on a single election. Such is part of the difficulty of evaluating probabilistic forecasts.

Chris Hibbert has posted a comment:

The question I was addressing wasn’t whether mistakes get made in judging. It’s whether it’s possible to write completely correct and unambiguous claims up front as you advocate as a solution to the problem. Do you want to address that question?

I don’t believe it’s possible to get the claims correct up-front, so I don’t see your rule as a solution. My experience writing, advising, and judging at FX informs my belief. It’s all done in public on FX, so I’m not the only one with that experience. The other markets (IEM, TEN, BF, HSX, etc.) have closed processes, so the community can’t learn from their experience.

There is a lively community at FX and at each of the other markets, play money or not. The discussions can go on for quite a while. You may be right that there’s more outside attention for the real money markets, but that doesn’t help at the point that the claims are being written.

The question of party alignment of independents could easily have been addressed in an interpretation after the claim was written. Many people realized it was an important question over the last few weeks. On FX, players can ask the judge, and the judge can add his interpretation to the claim. I don’t know of other markets that have a facility for issuing clarifications that traders can see when they’re reviewing the claim.

My Partial Answer:

I acknowledge your experience at the Foresight Exchange, but you don’t convince me. Crafting contracts for TradeSports or BetFair should be done with a higher standard of professionalism, because influential bloggers would raise hell if problems arised.

I stand on my opinion that the floated prediction is the contract, and that the intent of the contract and the letter of the contract should always coincide, no matter what.

As for issuing clarifications, TradeSports does it almost on a daily basis and I object to that. In the cases that I have seen at TradeSports, if the contracts had been crafted in a serious and professional manner, there would have been no need for issuing so-called “clarifications” after the grand opening of a contract.

And some TradeSports (human) market makers and big traders told me that they asked many times to the management to unveil the draft of the upcoming contracts to them, for a short period of time before the marketing of a contract, so that they can correct the mistakes and make suggestions. Sounds like a good idea.

Addendum (November 10): Scientist David Pennock is with my opponent, Chris Hibbert, on that one…

I weigh in with Chris H. over Chris M. on this one. There will always be the possibility of bizarre circumstances arising that were unforeseen or overlooked by the contract writers. Only hindsight is 20/20. For example, did Pat Buchanan win the Reform Party nomination or not? Or, what happens to GOP.Senate contracts when Bush becomes a dictator, hires Saddam as his VP, and returns the US Senate to the Newt Gingrich?
