Cornyn's warning

That would be Texas Senator, John Cornyn, who has said that if Lisa Murkowski launches a third party bid, she will have to resign as the vice chairman of Republican Senatorial committee, saying that "it's hard to see you...as part of Republican leadership if you're not a Republican." Murkowski has been signaling a consideration of running as a third party member, the concern being that if she does, the seat may go Democratic. I think the only way that seat is going Democrat is if Joe Miller pulls a Ted Stevens, rest his soul, and if Lisa Murkowsi screws up. Neither of those two things are likely, with Miller being new to the game and Murkowski as being an expierienced professional.
