You make a very important and over looked point. Santorum has NOT been vetted. Consider that Chuck Norris understands Santorum better than Rush Limbaugh and Mark Levin do. Why? Santorum has been ignored with Newt and Mitt’s ridiculous obsession with each other.
I think I can say with some confidence that as the truth of Santorum’s liberal record comes out, you will see Rush and Levin start to back away from him a bit.
But a word of warning to Newt’s folks - you damned well better start getting some of this stuff out there now before Levin and Rush become too invested in their love of Santorum to admit they were wrong.
