John Cole has a post up at Balloon Juice where he outlines the beginning of the circular firing squad that will break out if Barack Obama wins the election. In short, old-school McCain staffers are beginning to blame the sorry state of their campaign on Palin.
Now, I'm not one to get in the way of someone throwing rhetorical brickbats at Governor Palin. However, I would like to point out that to whatever extent John McCain's problems are attributable to her, they are indeed his own fault. He chose her as his running mate (apparently) without vetting her at all. If members of his staff want to complain about her performance, they must remember that it never would have been an issue if she was still just the governor of Alaska.
To use a sports metaphor (at which I obviously excel): when an interception is run back for a touchdown, you can blame the guys who failed to tackle the runner all you want, but at bottom, the quarterback who threw the interception is the one most at fault.
