Look at the national #s, Santorum can’t compete as effectively as Newt can. Santorum won in IA because he pandered his life away there for a year and was seemingly the only recourse left after Romney’s PAC blitz through IA.
Sorry, correction: Santorum technically didn’t win in IA.
National polls don’t care when it is a state by state contest. Funny how polls are suddenly important when it supports your agenda. Anyway, I want to wait and see how Santorum does in South Carolina before he drops out or maybe even Florida. However, Newt should drop out if he does not do well in SC or FL also.
