Condoleeza Rice has never run for any elective office, thus we don't know whether she has the fire in the belly to campaign.
She's an intellectual, not a politician. I don't think she'd take the VP slot, because I don't think she wants to be President.
My hunch right now is that Bush will pick McCain. He's not popular around here, and he'll be 70 in 2006, but he'd be a shoo-in in 2008.
McCain...
I hope not, ugh...
