Clinton-obama Democratic Party Presidential Contest: are We Seeing Bradley/wilder Effect

Adley Wilder effect, said that some white voters, when they express their political preferences of the black candidates reveal their preference (not misinterprete cheap nfl jerseys d his narrow-minded) in a race of the candidate in black and white, but said the actual preference of the voters, it can the white candidate.
The question is: Is the Bradley-Wilder effect is still alive? And it is to appear on the Democrat Obama-Clinton race for the presidency?

The most compelling data to say that the Bradley-Wilder effect is from the Democratic primary in Pennsylvania in its operation. About one in five voters in Pennsylvania said race of the candidates was an important factor in deciding how to vote, according to exit polls, and white
voters who cited race supported Clinton over Obama by a 3-to-1 margin.

The polls, conducted by Edison/Mitofsky for the five television networks and The Associated Press, asked voters if the race of the candidate was important: 19 percent said yes, while 80 percent said no. Of those who said yes, 59 percent voted for Mrs. Clinton and 41 percent voted for Senator Barack Obama. Of those who said no, 53 percent voted for Mrs. Clinton and 47 percent voted for Mr. Obama. Broken down by race, 13 percent of whites said race was important to them, and 75 percent of those voters sided with Mrs. Clinton.

Further, a recent Associated Press-Yahoo News poll found that about 8 percent of whites would be uncomfortable voting for a black president. (The actual percentage is probably higher because voters are shy about admitting a racial prejudice to pollsters.)

So are we watching Bradley-Wilder effect? May be but there are some serious confounding elements. Here is one. Unlike pre-election polls, the exit polls do not involve a "face to face" interview. Rather, the exit poll interviewer's task is to randomly select and recruit respondents, hand them a paper questionnaire, a pencil and a clipboard and allow the respondents to privately fill out the questionnaire and deposit it into a large "ballot box." (Note that the "Bradley/Wilder effect" pertained less to exit polls but to pre-election telephone surveys. The underlying theory was that white responnfl jerseydents were sometimes unwilling to reveal their preference for the white candidate in a bi-racial contest when they felt some "social discomfort" in doing so. That is, respondents would be less likely to reveal their true preference in a telephone interview if they believed the interviewe
