http://graphics8.nytimes.com/packages/pdf/...080505_POLL.pdfCaution is warranted when asking people to list the reasons for their behavior. People are notoriously bad at reporting the real reasons behind their motives--people will SAY they vote based on policy stances of candidates even if issues have a small effect. So you can't trust results from the poll questions asking people if they will base their vote on Wright.
The better way to assess attitudes is to look at the other questions about Obama's ability to make tough choices, whether he shares Wright's views, and whether people think Obama loves America more than Wright. Also look at how little change there's been on Obama's personal ratings. Not much has changed.
It may have affected Indiana and North Carolina races at the margins, but all the talk about the Wright issue "sinking" Obama's candidacy is just plain wrong. Plus, given all the airplay this has gotten, Obama is more immunized from the issue if GOPers try to run ads in November using Wright.
