Forget the polls, check the markets

(SH) - At this point, presidential polls are volatile and meaningless. In January, the Gallup survey had John Kerry leading George Bush, 55 percent to 43 percent; in March, Bush was ahead by precisely the same margin. Gallup's latest survey, on May 25, has Kerry leading, 49 percent to 47 percent.
There's another way to predict the winner, and, while it's not foolproof, it's proven far better that polling. Don't ask individual Americans for whom they'll vote if the election were today. Instead, ask traders on a specialized exchange - similar to a stock market - for whom America will vote on Nov. 2.
One such exchange is called the Iowa Electronic Markets, founded in 1988 by the University of Iowa College of Business (

Academic papers have found that the IEM, on average, has whipped the polls soundly. For presidential elections, the IEM's margin of error on the brink of the vote was just 1.5 percent, compared with 2.1 percent for Gallup. Three-fourths of the time, the IEM has been more accurate than the average pollster.
