The Bradley effect is a proposed explanation for a discrepancy between voter opinion polls and election outcomes in American political campaigns when a white candidate and a non-white candidate run against each other. The Bradley effect refers to an alleged tendency on the part of some voters to tell pollsters that they are undecided or likely to vote for a black candidate, and yet, on election day, vote for his/her white opponent.

Smart people claim the Bradley Effect won’t materialize against Obama on election day, but this concept might help explain the existence of at least a small percentage of so-called “undecided” voters.
