What everyone should understand is that this circular firing squad going on here today is meaningless. The simple facts are that voters made the Democrats the majority yesterday, and they (the voters) are sovreign. Politicians, both Left and Right, seem to forget that they have to earn every vote. The Republicans didn't spend their political capital over the last few years, they squandered it in a variety of ways, and lost their majorties because of it. It's back to the drawing board for 2008.
Treachery is very accurate...a little late to worry about the results of the deed now.
