It's Sarah who?

Kos could not of said it best.

Let's be honest: John McCain clearly wanted Tom Ridge or Joe Lieberman, but he was afraid to buck his party's choice ideologues. So then they looked at Mittens, but having a baker's dozen homes wasn't looking so hot. So he figured that with Pawlenty, he might make a play for Minnesota, but that got shot down over the last week as it become increasingly obvious that Biden would wipe the floor with him in their debate.

Throw in Obama's ground-shifting speech last night, and it was clear that McCain had to throw a hail mary to just remain in the game, much less be competitive.

So we get Sarah Palin, who has a fairly compelling personal story and is an attractive woman, but has scant political experience, zero name recognition outside of political junky circles, faces an ethical investigation by her own legislature, and will now be forced to run a grueling national campaign despite having an infant child at home.

Those are the marks of desperation, and really, given his precarious electoral position, John McCain had no choice.
