2. Her abortion stance really makes her a non-starter anyway, especially since Mitt promised last year that his VP pick would be a conservative, pro-life pro-"traditional marriage" person. He can't afford to piss off the Tea Party, as we saw in the mid-term elections. The Tea Party will happily strike down the GOP ticket if he doesn't pander to them.
He may be able to convince Rice to run in some kind of patriotic call to service. But I think the damage it would do to his campaign would kill it off.
Rice is still tainted by Gulf War 2. Independent voters would be turned off by that. Conservative voters would be turned off by her abortion stance. Is she qualified to be "a heartbeat away from the Presidency", given the fact that she has never held elected office before? Expect left-leaning commentators to make hay with a line like "even less qualified than Sarah Palin".
I reckon he'll go for Rob Portman.
Sometimes I think we over-analyse things. I've never thought of the average American voter as a sophisticated, widely read person - he/she would probably be unaware of Rice's pro-choice stance, for example.
Or even worse, he/she might not even know who Rice is - "Rice? Mmmmm like rice, risotto ommnomm"
There's even less of a chance a far right Tea Party type knows what risotto is...any food or person with a vowel at the end of it's name is suspect to them....
