WSJ: ...Democrats' fatal blindness to the brute fact of race in America. When, during the primaries, the Clintons seemed to allude to the subject of Sen. Obama's electability in light of his race, they were accused by many of their fellow Democrats of "playing the race card." It is fairly incredible that it was, for the most part, not until this summer that liberals began publicly asking themselves if the country was ready for a black president. That it was not until recently that liberals began wondering with any forcefulness whether people really were telling pollsters the truth about their attitudes toward race. ("Will race influence your vote for president?" "Race?! Me? Are you kidding? Of course not!")
For 18 months, the majority of liberal commentators wrote so rapturously and unskeptically about Sen. Obama's candidacy that you would have thought he was just a white guy with a deep tan. It was as though people were afraid that if they spoke honestly about racism as a stumbling block to his candidacy, they would be taken for racists themselves. Indeed, it was as though by ignoring racist attitudes when writing about Sen. Obama, liberal commentators conferred on themselves the virtuous idealism that they were fantastically attributing to the country as a whole. It is an elementary psychological fact that we sometimes praise to an absurd degree what makes us slightly uncomfortable -- or that we put the source of discomfort in an impossibly ideal light in order to put as much distance as possible between us...and the person we fear we may actually be.
What polls show about racism and voting:
...Some people who are telling pollsters they're for Obama could actually be lying.
Such behavior has been called the "Bradley Effect ," after Tom Bradley, a black mayor of Los Angeles who lost his bid to be California's governor back in 1982. While every poll showed him leading his white opponent, that isn't how the final tally turned out. Things haven't been far different in some other elections involving black candidates. In 1989, David Dinkins was eighteen points ahead in the polls for New York's mayoral election, but ended up winning by only a two-point edge. The same year, Douglas Wilder was projected to win Virginia's governorship by nine points, but squeaked in with one half of one percent of the popular vote. Nor are examples only from the past. In Michigan in 2006, the final polls forecast that the proposal to ban affirmative action would narrowly prevail by 51 percent. In fact, it handily passed with 58 percent. That's a Bradley gap of seven points, which isn't trivial.
Pollsters contend that respondents often change their minds at the last minute, or that conservatives are less willing to cooperate with surveys. Another twist is that more voters are mailing in absentee ballots, and it's not clear how those early decisions are reflected in the polls. Yet the Bradley gap persists after voters have actually cast their ballots. Just out of the booth, we hear them telling white exit pollers that they supported the black candidate, whereas returns from these precincts show far fewer such votes. Thus they lie to interviewers they don't know and will never see again.
