Here's why not. McCain this week:
In a direct challenge to Democratic leadership, Sen. John McCain (R-Ariz.) introduced an amendment on Thursday night that would prohibit Congress from using reconciliation to make changes to Medicare.
Here's McCain the whole rest of the time:
McCain has voted for nine separate piece of legislation through the reconciliation process -- four of them included cuts to Medicare. He is, in other words, pushing a new measure to prevent a step he's already taken several times.
Yep. That about sums it all up. He's crazy.
