Okay, I’m not serious about the 2006 primary. But I do think Santorum should pay a price for what he’s done. He has leadership ambitions in the Senate. Was his overflowing support for Specter aimed at convincing moderate GOPers that he’s a big-tent kind of guy? Hard to see how it wouldn’t have that effect. Conservative senators will have to remember what kind of majority Santorum is apparently committed to preserving, and whether this is the type of leadership they’re looking for.
