How Close Were US Presidential Elections?

Mike Sheppard writes "I'm a graduate student in Statistics at Michigan State University and spent some time analyzing past US presidential elections to determine how close they truly were. The mathematical procedures of Linear Programming and 0-1 Integer Programming were used to find the optimal solution to the question: 'What is the smallest number of total votes that need to be switched from one candidate to another, and from which states, to affect the outcome of the election?' Because of the way the popular and electoral votes interact, the outcome of the analysis had some surprising and intriguing results. For example, in 2004, 57,787 votes would have given us President Kerry; and in 2000, 269 votes would have given us President Gore. In all there have been 12 US Presidential elections that were decided by less than a 1% margin; meaning if less than 1% of the voters in certain states had changed their mind to the other candidate the outcome of the election would have been different."

Even the Florida recount didn't seem to matter that much to me, I figured "how much more then the other one can one of these bozos screw things up?" After 9/11 and the other insane government fuckups of the first Bush administration, I got more involved. I figured there'd be no way 2004 would re-elect Bush, so I didn't donate too much or work too hard. Sure Kerry was wooden, but after the first debate my vote changed from "Anyone but Bush" to "Kerry, the guy who could articulate an intelligent position" (even if he could ramble on for days :)

Once the system is known very well, it is an engineering problem: "an electronic system monitors the mixture and adjusts for different conditions on the fly."

    Just as the cola wars are in a well-settled detente, the business of national politics is a marketing endeavor. Whether you're Demopublican or Replicratic, whether you're a Preservative or a Libertine, your party system will simply apply the art, nee, the science, nee, the engineering methodology to ensure the candidates do the best they can. Of course, both sides have effectively infinite resources so the marketing comes out equal, and the course of history witnesses Gore/Bush 2000, too many 5-4 decisions to count, a roughly 50-51 Senate, and a dynamic but well-balanced electoral college.

In the end, the party campaigners only go after the swing seats where there is no outright majority for any party. Changing election boundaries might be one way of solving this, but low income areas tend to have a higher housing density and so have a smaller catchment area.

    The answer to that is that the optimal popular appeal for a party is 50% plus one vote. Less, and you lose the election. More, and you have increased the internal stress in the party and reduced the size everybody's slice of power, for no real purpose.

    Generally speaking, Hawaii is written off in national elections and only gets marginal attention in Presidential elections. It certainly isn't mentioned as a traditional swing state like Ohio, Michigan, or Florida... perhaps because of the small number of electoral votes. In a close election, however, even a few electoral votes can make a difference.

    Yes, 289 is the _smallest_ number of voters that could be switched to change the result of the election. But that gives a misleading picture of how close it was. You should also consider the largest number of voters that could switch without changing the result: that is several million votes (for example, Texas voted for Bush; switch 24.999% of the votes Texas cast to Bush to Gore, and the result does not change). In other words huge numbers of people (outside Florida and other swing states) could have decided to vote for Gore (or Nader) instead of Bush and it wouldn't have made the slightest difference.

    Perhaps the fairest measure of the closeness of an election is: what is the smallest number N of votes such that if you picked N individual votes at random across the whole country and flipped them, there is more than a 50% probability that the result would change?
