I hope Democrats will have competent candidates ready in Indiana and Maine to take advantage in the event that the Tea Party is successful in winning primaries.
They have some in Maine, but they probably wouldn't jump in unless they know for sure they won't be facing Snowe. And at this point, she's favored.
You can have Delaware repeat, with a top-tier backing offf, when they were sure they are going to face Castle. But when Christy toppled Castle, a second-tier Democratic sacrifice lamb, Chris Coons, suddenly became a favorite.
So, if Snowe is teabagged, don't be suprised some sacrifical lamb will suddenly become effectively a Senator-elect.
