Implausible deniability?

John McCain declared long ago that he regarded the controversy over Rev. Jeremiah Wright's sermons to be out of bounds for his campaign. That hasn't stopped his running mate from making passing references to it, and now the Pennsylvania GOP is airing this ad:



Will McCain condemn it? Will he publicly call for them to take it down? Will he plead powerlessness -- I can't control what they do, they aren't part of my campaign -- to do anything about it? Will he be asked about it? We'll see. Since his running mate is on record that it is a legitimate issue to raise (remember, she's worried about the press denying candidates their First Amendment rights to launch attacks without being criticized), I'm betting McCain will opt for implausible deniability.
