[how many actual non-RINO Conservative GOP females do we have in the Senate ?]
Does Liddy Dole count?
Anyway, the best RAT candidate to run would be Tanner. He is a liberal who is able to fool gullible Yellow Dogs into thinking he is a Zell Miller RAT.
Tanner is a jerk, plus a bit past his prime for eyeing anything higher (the time for him was in '92-'96). His bitterness at having been in the minority for 10 years is palpable and he has taken cheap shots at the President (more infamy for Tanner, it was apparently he who was on the other end of the phone during one of Clinton 'n Monica's late night blow trysts).
