If any Rat runs against Snowe or Collins or any other "enlightened" GOP moderate, the Dim candidate and the Dim machine will campaign against them just as hard as they would against a real conservative.
I don't support Schlesinger because he's scandal tainted and won't make it above 5%. But still, the GOP should stay out of this race and let the chips fall where they may fall. It's just like Alien vs Predator. Whoever wins, we lose.
The best thing for the GOP to do (failing to get a replacement candidacy) is to stay out of the race and let the rats tear it out, a case of one extreme ultra lib or ever another less extreme ultra lib slugging it out in CT..the GOP should not be wasting its effort.
