ENTER THE BRADLEY EFFECT

Bone up on this. I predict the Bradley effect will weigh heavily in McCain's favor.

The term Bradley effect, less commonly called the Wilder effect, refers to 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. Named for Tom Bradley, an African-American who lost the 1982 California governor's race despite being ahead in voter polls, the Bradley effect refers to a tendency on the part of white voters to tell pollsters that they are undecided or likely to vote for a Black candidate, when, on election day, they vote for his or her white opponent.

One theory for the Bradley effect is that some white voters give inaccurate polling responses for fear that, by stating their true preference, they will appear to the pollster to be racially prejudiced. The reluctance to give accurate polling answers has sometimes extended to post-election exit polls as well. The race of the pollster conducting the interview may be a factor into voters' answers. Some pollsters believe that they do not receive deliberately false answers from white voters. The Bradley effect, these pollsters believe, is caused by pollsters' failure to account for general conservative political leanings among undecided voters.

Get schooled here.
