The man was asked a direct question. He didn't "insert" himself into it.
He could have simply given another non-answer like policians so often are wont to do, but he gave a candid, if guarded, answer.
It is the GOP and rabid right that have "inserted" him into it, in an obvious and disgusting cynical attempt to score political points with their base.
Based on the comments here, that cynical ploy worked with the useful idiots, like Jack and Ducks.
I would be a of a lot more sympathetic to the GOP if it weren't so obvious that it was being increasingly driven by extremists, as this whole episode so aptly demonstrates.
I voted and campaigned for McCain in 2000. (kick myself repeatedly for giving the T-shirt to goodwill, man, what a keepsake that would have been)
Even today, when I am not really all that happy with Obama to put it mildly, I have not regretted my vote for him for a second, because I know that had the election gone the other way, it would have given active power to shape policy to those who I view with no small amount of alarm, i.e. Palin et al.
Someday, when demographics bury the GOP as a national party, and Republicans look around and wonder what the happened, I will not be all that sad, because I know they did it to themselves with stupid like this.
