the Bradley Effect: shame on who?

A post over at Dan Cleary's blog expresses a concern I've heard expressed by some Republicans/Conservatives that a McCain victory might be diminished if there is evidence of the so-called "Bradley Effect."

I'm not sure that it being a factor would necessarily diminish a McCain victory, unless "being truthful to pollsters" is the moral standard. Though racial prejudice MAY be one motivation for being a "Bradley Effect" voter, it is inarguable that concern about appearing racially prejudiced for not voting for Obama is really the motivation . . . and who's (here, here) to blame for that? Indeed, I think trumpeting this issue is simply another way to influence uncommitted voters toward Obama.
