I don't think anyone who is intelligent and knowledgeable thinks Rick Santorum is the reason that there are omnibus bills. Santorum should have articulated his position better but these attacks are just grandstanding and are without substance.
Santorum was ganged up on two against one by Romney and Paul. They did not come up with any convincing attacks just political posturing. The Romney supporters in the crowd were also vocal and the moderator helped the Romney/Paul team attack Santorum.
I would have liked to have seen Santorum less defensive and more articulate in his positions. But overall I think he did fine. I saw nothing that would make an intelligent voter not support him.
I agree with you. I still support him. However, I think that he (and Gingrich too, probably) needs to come up with a concise, solid explanation why omnibus bills are unavoidable, and especially in a divided government.
