Top political scientists predict outcome of the 2012 presidential election

[one...two...tree 2,762]

With a range of forecasting models and experts, the forecasts vary, but none are predicting a big win either way; yet another indication that 2012 is shaping up to be another very close race.

Five models predict a modest to close plurality for Barack Obama (though three of these are on the cusp of predicting a toss up), five predict a modest to close popular vote victory for Mitt Romney, and three regard the election as a toss up. The forecasts range from predicting a 53.8% vote for Obama to a 53.1% vote for Romney.

Editor of the journal's forecasting symposium, James Campbell, said: "It is difficult to say exactly why the forecasts vary as much as they do this year, but it appears that those that rely more on the existing holder of office and early public opinion indicators tilted more toward Obama, while those that depend more on objective economic variables tipped toward Romney."

The thirteen forecasts and introduction will be published in the October issue of PS: Political Science and Politics, scheduled for release in late September.
