Hunter Golden said it best...
I think the ONE guy who could sneak into the mix is Thompson, with Romney now completely sunk, I think you're going to see some defections to the Thompson crowd. If he takes the conservative stance, he can do well in South Carolina. I think while Huckabee and McCain are essentially playing to the same crowds.
This has actually been part of Fred's campaign strategy as of late. Get 3rd in Iowa, ignore New Hampshire for obvious reasons, and make the push in South Carolina. A 2nd place, or better, finish in SC will provide the shot in the arm to Fred's chances. The defection from Romney to Thompson has been predicted by other prognosticators, as well.
Good news for Fred.
