I keep hearing the justification for Sarah Palin boiling down to: McCain realized that he was on the losing tack and needed to try something else. This has nothing to do with the paper thin vetting of Palin's background, of course, but the justification seems to be that McCain is excused anything if it looks like he is going to lose. As a commenter on The Corner put it, it's not fair to demand that McCain drown with De Toqueville hugged to his breast. To put this differently, the essential Republican take on McCain's decision is "Go Big or Go Home." Well, it looks like with Palin, McCain will get to do both.
