The naysayers' doubts notwithstanding, I think Sarah Palin was a great pick on McCain's part. While this may force the McCain campaign to tone down the rhetoric about Obama's lack of experience, there's enough on the issues to hammer him over, and that's what it should all be about, anyway. Hell, at least Palin's got more stick time as an executive than Obama does.
I was actually hoping Palin would be the pick, but didn't put much hope in that prospect when it looked like Romney or Pawlenty were the likely choices.
