Condi will cost you the pro-life vote. If you want to throw the election to Hillary, nominate Condi. She has also said repeatedly that she has no interest in running.
Allen was Governor before he was Senator. Right now he's looking like the best we have.
Not if she defaults to a position of federalism on Roe vs Wade. That is her weakest issue and if she resolves it then she is our only shot IMO to win in 2008.
