"She isn't going to be replaced, if McCain were forced to do that he might as well throw in the towel."
Danni:
Actually, a carefully managed replacement might do McCain quite a bit of good.
Here's the script as I see it:
He gets through the convention, having reached his desired goal of grabbing as many eyeballs as possible with Caribou Barbie.
Next (in a week or two), after more revelations about Caribou Barbie (or more outrage about the existing ones), McCain comes out and says that he now believes them and he is shocked - shocked! - by what has emerged in spite of his super-duper vetting of her.
He then declares, forcefully, that he Will Have None of This, and tells a breathless nation that Pawlenty has been chosen to replace his fallen pick, 'cuz Big John ain't having no corruption in his Casa Blanca.
It will play pretty well, I think. It may even have been planned this way from the start (maybe even by Rove, who has been suspiciously quiet and circumspect this election cycle); there's very little other explanation for the suddenness of McCain's choice of Palin. He's used her like a Kleenex, in my view. She'll be wadded up and thrown away soon.
