Meg Whitman is pro-choice. She’s out, if the RNC and McCain are to be believed.
I've heard that, too, but what's the source? (Not that I expect her to be the choice -- for other reasons as stated above.)
US News supposedly says Romney is out. So if Whitman is pro-choice, if Lieberman won't campaign on the Sabbath, if Pawlenty would be filleted by Biden, and if KBH and McCain don't like each other, it looks like nobody is left.
