The response from the Left is helping, if anything. Yes, she is inexperienced, but the Republicans obviously realised that that wasn't working as a charge against Obama, and decided to roll with it; and Obama's supporters now cannot really use Palin's inexperience against her without inviting the obvious counterattack - so what if Palin has only run a very small town and a very small state; that is still more than Obama has ever run (or, for that matter, McCain).
The news about her daughter is also a complete winner, in my view. Before it broke,
There are good reasons to attack Palin's judgement - her definition of clean government seems flexible enough to allow her to pursue family vendettas from the Governor's office. There are plenty of good reasons to worry about the McCain-Palin ticket; in my own area of particular interest, foreign policy, I confess I don't have a terribly clear image of what Obama's line actually is, but I have a good understanding of McCain's line - and it frightens me - and I know and respect a lot of Obama's people, which reassures me. So let's stay with the sensible stuff, OK?
