This line from a top McCain adviser, in a Politico article on Obama's efforts to convince the electorate that he's American through and through, is unintentionally funny and revealing:
"We don't want to talk about his patriotism and character," said McCain adviser Charlie Black. "We concede that he's a patriot and person of good character. This is about big issues."
It kind of says it all that to this senior McCain campaign hand, acknowledging that Obama is patriotic is a concession.
