If the Dems lose the Senate, look for a boatload of barely-living old collectivists to retire from both the House and Senate before 2016. Their fun time is over and they’re not going to sit in the back seat.
On the other hand, look for a boatload of Republicans to leap far left to represent the cause of collectivism.
If it’s 50-50 after the election, I look for John Mccain to do the Jeffords Jump before the new Congress seats
