In the FiveThirtyEight “now-cast,” Mr. Obama went from being 1.5 percentage points ahead in the popular vote on Oct. 25 to 2.5 percentage points ahead by Election Day itself, close to his actual figure. Nonetheless, polls conducted over the final three weeks of the campaign had a two-point Republican bias overall, probably more than can be explained by the late shift alone. In addition, likely voter polls were slightly more Republican-leaning than the actual results in many races in 2010." |
