On the 06/06 Mark Levin Show starting at 1:39:27:

Mark Levin:  “Now is there anything that you voted for, or maybe one or two things that you voted for that you think your opponents will attack, or the left will attack, or that you regret?”

Santorum: “…uhhh..well..the left will attack I don’t know…but I as..I..as far as what..what..my political opponents on the right will attack is that I voted for the Medicare Prescription Drug Bill and..you know I said at the time..I gave speeches at the time this was the hardest vote I have ever had to cast because..you know there its..uhhh..one of those things..were you know there are a couple of things in this bill that are really bad…”

Santorum then went on to justify his vote at the time, but admitted that he would not vote for this bill today. He went on about how he is the candidate that will stand up for Conservative principles, and how so and so “sold us out” etc.  But there is one incident Santorum will come to regret, even though he refuse to recognize it, and that is: What did Santorum do in 2004 when the choice was supporting Snarlin’ Arlen or a true Conservative, Pat Toomey? Did Santorum stand with his Conservative principles or did he make a calculated political decision? A political decision that “sold out” the Conservative? The Conservative that when on to WIN the very same seat six years later!

Everything he said in the interview about his family, about anything regarding Conservative principles, about why we should vote for him in the 2012 primaries was automatically discounted because in 2004 when Santorum could have stood up for a true Conservative, Pat Toomey, he didn’t.  He showed he was just another politician. That will cost him any hope of being the Conservative nominee in 2012.
