I seriously doubt that the FRC used the words "take him out" when discussing Giuliani.
The only other possible candidate I can think of that the conservatives might go for would be Sen. Fred Thompson. It is said that every Senator would like to be President. I've always thought that Fred "looks" like a President to me. Whether he has the "fire in the belly" to go for it is another question.
Who ever it will be, will depend upon name recognition and the ability to raise cash. The less known, the more cash will be needed. So, if you have someone in mind, now is the time to put your bets down.
