Even if you do not live in an early-primary state, it's almost impossible to avoid online polls and "elections." How much their results square with reality remains to be seen, but one online poll is intriguing less for any predictive power than for what it says about the interaction of math and elections (and I don't mean the funny way they count votes in Florida). The American Mathematical Society and other scholarly groups have launched a site where you pick your favorite presidential candidate—as well as choose any of eight you deem acceptable and rank them from one to eight. (To play, go to
www.amstat.org/mathandvoting.) Now the fun begins. The three different methods produce, when I tried it, at least two different winners.
For anyone who believes in democracy, this is a little disturbing. What it means is that "election outcomes can more accurately reflect the choice of an election rule than the voters' wishes," writes mathematician Donald Saari of the University of California, Irvine. One candidate could win with some rules and lose with others. In fact, as mathematicians analyze voting systems, they are turning up other oddities that can yield a "winner" who does not reflect the will of even a plurality, much less a majority.
