Rice is pro-abortion, and I've already gotten a few choice comments for thinking that the also-pro-abortion Giuliani will get the nod. Besides that, does Rice even want the job?
I would nominate Rice as head of Homeland Security (As mentioned earlier) if she doesn't.
And like I said, Giuliani may be a RINO-but he is not a backstabber like McCain (At least that's the impression I get.)
