Which GOP Senator(s) Will Lose to a Tea Party Challenger in 2014?

Graham, maybe Cochran (if he runs for reelection and gets a strong primary challenge, he could be in trouble), and maybe Chambliss if Price runs against him (I read that Gingrey has quietly made it known that he isn't going to run and even if Price runs, Chambliss would still be favored).  I suspect that most of the damage done by the tea-party this cycle will be done by making the party behave in a highly obstructionist manner and causing the party to nominate weaker candidates for Democratic Senate seats.

Saxby Chambliss has committed the mortal sin of defying Grover Norquist. --> http://www.politico.com/news/stories/1112/84176.html?hp=l4

I still hate him for the nasty way he ran against Max Cleland, but as a legislator he is probably the sanest Republican officeholder in Georgia. Their whole House GOP delegation is awful and Nathan Deal is a Dixiecrat convert. The last really solid Republican they had was Paul Coverdell.

Isakson is much better.  He seems a lot like Chambliss ideologically and isn't an evil man who got elected by trying to destroy the reputation on a genuine war hero.
