As you pointed out, Santorum is indeed a flip flopper.
Where he gets away with it is that he has been such a back bencher for all of his career that no one knows or remembers what he did years ago. It is just now trickling out.
Both the Newt and Mitt campaigns made huge huge mistakes by not letting some of this trickle out sooner. Many of these Santorum supporters would have seen the light early in their support, but their support has now been firmed and they’ve had too much of the kool aid.
He’s a big government liberal. His “holier than thou” persona is a big whopper of an act. True believers don’t believe in robbing one person (through taxes), to pay for another (like Social Security, Medicare, etc., etc.).
Nor do they believe in removing the ability of people to govern themselves. Rick Santorum hates freedom, and think he can channel one one of the biggest statists of them all: Abe Lincoln.
Santorum is the only person running for President who falls below Romney, including Obama. If we’re going to be run through, I’d rather it be done quickly, and without the theocratic babble at the same time. I love Godly people in Government, I hate people trying to replace God WITH Government (especially when they pretend to do it in God’s name). “Never” to Santorum, “NEVER.”
