Kinky elections
I’m coming back from my 2-year hiatus! Why? It’s election method time!
2006 is an election year for Texas governor. Rick Perry (the one with the hair) is the incumbent, polling 34%. There are three other major candidates on the ballot: Chris Bell (D), Carol Keeton Strayhorn (ex-Republican, decided to take her chances in the general rather than the primary), and Kinky Friedman (comedian). All 3 are polling about 20%.
It’s quite possible that none of the other 3 could beat Perry in a one-on-one race. If this is the case, then our current system comes to the same result as virtually any other decent method. On the other hand, it’s quite possible that any of the other 3 candidates would beat Perry in a one-on-one election. That means Perry could be elected despite 2/3 of the voters preferring anybody else to him.
In that circumstance, IRV would offer an improvement: Perry would not be elected. However, it wouldn’t be perfect: it’s still possible that the vast majority of the electorate would prefer one of the losing candidates to the one that won. For example, Strayhorn might end up with less first-place votes than Bell or Friedman because most Republicans vote for Perry, but be much preferred to either because most who voted for Perry prefer her to Bell or Friedman.
A far worse case for IRV, though, is if only one or two of the candidates can beat Perry. If Strayhorn got fewer first-place votes than Bell or Friedman, she’ll be knocked out immediately. But it might well be that she’s the only candidate among the 3 who can beat Perry head-to-head.
While this might seem like a strange what-if brought on by the special circumstances of a 4-way election, circumstances like these are latent in virtually every election we hold. After all, if John McCain had been running head-to-head against George Bush in the general election in 2000, he would have won a landslide. Under a sane voting system, he wouldn’t have been forced out of the race because a majority of a minority preferred another candidate.
