Stanford Predicts The Presidential Election 158

Can Sar writes "Today is the official launch of Stanford Predicts, a non partisan group trying to predict the 2004 Presidential Election. This project is led by and based on research by Professor Samuel S. Chiu of the Department of Management Science and Engineering at Stanford University. Stanford Predicts is solely interested in predicting the likelihood of either candidate winning, for purely scientific purposes. While the formulas themselves were developed in previous years by Professor Chiu all data analysis is being done by undergraduate students. Stanford Predicts will be continuously updated with new predictions until election day. Please check out Stanford Predicts for more information."

    American University Professor Allan J. Lichtman, author of Keys to the White House [amazon.com] uses a 13 key system to predict the Presidential winner [commondreams.org] (popular vote), and right now, the keys system favors Bush (9 to 4 [commondreams.org]). Gore won his analysis in 2000 and the popular vote, but not the Presidency. It's possible something similar could happen again.
    • I am just waiting to see who wins the redskins game....
    • Interestingly enough, Lichtman's colleague in this Keys to the Whitehouse prediction system, was Dr. Keilis-Borok, who predicted two earthquakes in Central California and Japan, and failed to correctly predict an earthquake in Southern California.

      Quite a bit of his research (both in geophysics and non-geophysics related subjects) has been devoted to the mathematics of pattern recognition.
    • Because of which states are going which way (small states with excess electoral votes going for Bush), I think it is virtually impossible for Bush to win the popular vote yet lose the election. He could lose the popular vote and win the election as with Gore, but not the other way around.

    This guy [electoral-vote.com] has the same sort of daily predictions. Funny his prediction for today is the opposite that Stanford predicts. I sent him an excel file demonstrating the use of error estimates and probabilities to get a better prediction, but haven't heard back. Though even with that the prediction would still be in Kerry's favor, so I'm not sure what all Stanford is and isn't taking into account. He apparently gets a lot of crap in his email from opponents.

This has the effect of tipping a number of crucial swing states to Kerry for his final prediction. He makes a pretty good case for this (undecided voters going 2:1 for the challenger) based on historical trends.

    I've been following along the election with www.electoral-vote.com, and while it's good to have predictors, I wonder how much impact these have on the outcome, do sites like this have a detremental effect on the election by creating a self fulfilling prophecy? Have there been studies on this effect, say a voter sees that bush has a 72%chance of winning, and decides that the country can't be wrong and goes along with it.

    Anyway, I like electoral-vote's way of going about it better, shouwing actual state polls and the number of electorial votes each candidate has rather than a straight up prediction of the outcome in a percentage. Lets you see how close the race is as far as votes and what your effect based on your state can be, it's a lot more empowering when you see your state is very close and has a lot of electorial votes, and how close the candidates are.
    • It can go the other way too, with voters thinking their guy is behind being more likely to trek to the polls while the voter that thinks their guy is ahead just stays home. I'm seeing this somewhat here in Illinois with people saying that since the state is going to Kerry no matter what that it isn't worth bothering to vote one way or the other.

    • a voter sees that bush has a 72%chance of winning, and decides that the country can't be wrong and goes along with it.

      The only wasted vote is a superfluous vote for the winner. Since I don't live in a swing state, I can vote my conscious (Libertarian Party) instead of holding my nose and voting for John Kerry (hoping for divided government to keep him and Congress in a political stalemate).

      I think the methodology of the stanford predicts is at best fishy. The problem is that they go for an immediate state, discarding previous results and this makes their predictions very sure. You can see that most of them are over 90%. Now tell me that Florida is anything further than 10% from draw? I don't think so.

      The main problem is that he needs to take in account all the previous data and see how the state numbers vary and how far they swing up and down and take that in account when counting the chance that either candidate will win the election. I think it would reduce the probabilities and make all these numbers more realistic.

    • The exact opposite happened in Florida last time around. The result was called in favor of Gore before half of the state's polls had closed. The people still left to vote, seeing that the news was saying Gore was the winner, either went out and voted against them as soon as they saw they needed to, or stayed home thinking they're vote for him was no longer needed. Ignore Michael Moore's take on it.
    • I wonder how much impact these have on the outcome, do sites like this have a detremental effect on the election by creating a self fulfilling prophecy?

      With all the lawyers already filing lawsuits and the potential for another contested election I think it would be perfectly rational for undecideds to pick whoever looks like they are winning.

    I couldn't find info on which polls they used. Of course, some pollsters do a better job than others, and some even engage in push polling?*

    So, it seems to me that feeding a different subset of polls will garner different results, and that the equilibruim is very stable -- change the Ohio or Florida poll by two percentage points toward Kerry and I'd bet the odds go from 3:1 to 1:1 pretty damned quickly. Likewise, fudge the CO, NH, and MN results toward Bush 2 points, and it might go from 3:1 to 5:1.

    Surely they could do a better job about releasing their data and their polling selection methodology...

    It amounts to a laborious book-keeping problem -- to figure out all collections of states that will give Kerry 282 votes, getting heads in those coin flips and tails for the remaining. Using a clever procedure, we are able to carry out these computations efficiently without having to explicitly consider all possible combinations of state outcomes.

    The numbers above represent the probabilities that either candidate wins enough votes on the Electoral College to be elected President, as of the latest available polls. They do not represent actual vote counts or direct poll results, but are inferred from poll results.


    This is my problem with these sorts of things. While the polls are always statistically sound i have a 800-lb gorilla-sized sneaking suspicion that the polls being conducted do not accurately represent the electorate, in which case the statistical rigor gives way to a sort of bias in these results.


    I've thought for a long time (since last spring) that Bush will lose by a not unsizable margin and people may actually be surprised on election day by the way the polls had failed to capture the public's true intent.


    This is all purely anecdotal of course but i just think that since all of these polls are via land-lines (at who knows what time of day), they no longer capture a validly random sample. After all a shrinking percentage of people i know (all of whom vote) even have a land-line, and far fewer actually talk to any pollsters or their ilk - the urge to hang-up on these sorts of callers is just too overwhelming...


    Though it may very well be me who is surprised on election day this is what has been brewing in my head lately...


    We'll see, although i would bet that there'll be partying in the streets around the world on Nov. 2nd/3rd should Bush lose.

      They use the results of a number of polls. Since these polls are more or less independent of each other, it's mathematically acceptable to aggregate them (provided you do the simple stuff like weighting the polls according to sample size, etc.).

      You say that the polls themselves are all biased in the same direction, reflecting the viewpoint of likely voters who answer their landline. While I can't invalidate that completely, the fact that multiple polls find similar results tends to weaken the idea. The question is open whether people who don't answer their landline lean toward one side enough to change the results. Also, polls of kids, who usually tend to track their parents' viewpoints, agree with the telephone polls.

      It's possible that your friends think the same way you do, so to you it feels like everybody hates the President, when in fact most people like him.

In that time I've learned two things (a) generally polls are eerily accurate (ignore them at your own peril) and (b) every so often there are certain elections which one can tell, almost from the get go, that previous historical norms won't apply and hence polls will mispredict the outcome.

    The 2004 presidential election is one of those elections in which participation rate of voters will be way out of the norm, on the coat-tails of the 2000 stalemate and the strong anti-Bush feeling from the democrats.

    Using historical data, Bush is slightly ahead as reported by the Stanford poll or electoral-vote.com. If we correct the data assuming a slightly higher participation for the democrats, the polls give an edge to Kerry of 284 electoral votes vs 254 for Bush.

      Except that there are as many Democrats defecting to Republicans as there are Republicans defecting to Democrats, at least in my experience. The Democrats are not particularly motivated, and a great many I know think Kerry is a pompous asshat, such that they really don't care who wins even though they do not like Bush. They despise Bush, but they don't like Kerry either even though they'll vote for him.

      And in fact, that is why the Democrats will lose the election. Out of all the people they could have selected, they select a flagrantly elitist blowhard with no definable position and an obvious lack of charisma. Ugh. There really is nothing to get excited about there, and it is apparent that a lot of Democrats don't really believe in Kerry. Other than the libertarian wing of the Republican party (which is, sadly, fringe), the Republicans genuinely seem to like Bush, for better or worse. I've definitely noticed an erosion of support among the old school blue collar life-long Democrats, many who feel that Kerry is completely out of touch with their reality.

      The Democrats had a real shot, right up until the point they selected Kerry. Mind you, I don't think it was obvious just how lousy of a candidate he was going to be before they selected him. Howard Dean would at least have been interesting, and even someone like Gephardt would have done better shoring up the base. Right now, they are chasing down votes they should have already owned.

      Which kind of begs the question as to how we ended up with a couple of clowns to choose from in the first place. What happened to really great candidates that you could feel good about voting for?

And Dems are angry like I've never seen before: they feel that they won in 2000 and yet have had to endure four years of the most incompetent and arrogant presidency in generations. I had no great fondness for Bush Senior but you had to respect him. I have not a shred of respect for W.

He struck me as a spoiled child who needs to be taught a lesson in responsibility. When confronted with all the failures of his administration, he had this whining tone of "You just need to see it from my perspective". No, I don't. You're the president, you're supposed to be responsible. He isn't. He's an alcoholic cokehead trying to tell other people how to live their lives, he's a failure as a president, and he serves only to make the rich more rich, and the powerful more powerful. I'll vote for a lobotomized chimp before I'll vote for George W. Bush.

The Economist is my favorite news magazine, I really thought John McCain would make a good president, I find Michael Moore intellectually dishonest, and I find Bay Area knee-jerk liberals to be infuriatingly smug and uninformed (although I have to admit they were right about Iraq). Also having read up on it, I believe that the first Gulf War was both justified and necessary(by strategic concerns- oil- if not moral ones).

You just have to be informed and care about the values he claims to promote, like liberty and justice. For many of us, it's not that we're left- we're in the center, same as always. It's that George Bush has taken the nation too far to the right while claiming to speak for the whole nation.
