Simple solution: Elect a 60+ Republican majority in the Senate.
It can easily happen in 2012.
One seat which we need to flip to make that happen is the one occupied by Bob Casey, Jr. It is about one year before the election and we still don't have a first tier candidate to challenge that empty suit, do we?
These empty suits can be the most frustrating. He has a nice persona, but really hasn't said or done anything to really p*ss off enough voters. His handlers are pretty good at making sure he won't.
