Why would anyone want to? They are probably the most conservative candidates that can realistically be elected in their states. The same with Chafee. They aren't very reliable, but they are a lot better than a full blown communist democrat that would take their place.
The problem is with the red state RINOs like Lindsey Graham. There is no reason why he should be able to behave the way he does being from a conservative state. Somehow he gets a pass though. McCain is another problem.
If the GOP would get serious about replacing moderates from red states, then they'd be ok.
