The "Bradley effect"—named after Tom Bradley—who lead in the polls but did not prevail in the actual 1982 California election for Govenor—has hopefully reared it's ugly head for the last time. The assertion of the Bradley Effect is that white people when polled said that they would be voting for Tom Bradley because they they didn't want to be perceived as racist, but then did not vote for him because they really are racist.
Whether whites supported Barack Obama or not, they don't seem to have lied to pollsters about it.
Obama's election triumph on Tuesday presented no evidence of the so-called Bradley effect, in which whites who oppose a black politician mislead pollsters about whom they will vote for. Instead, national and state pre-election polls were generally accurate in reflecting voters' preferences in the presidential contest.
"I certainly hope this drives a stake through the heart of that demon," Charles Franklin, a University of Wisconsin political scientist and polling authority, said of the Bradley effect.
The Bradley Effect never had any basis if fact. It is just as likely that the results were due to the same over performance that we have seen for Democrats in the presidential polling in 2000 and 2004. The speculation that race was the culprit was a self serving justification. Hopefully we have seen the last of it.
