Maybe something to do with the Democrats being themselves, with no excuses and nowhere to hide.
I think you're right. Lieberman's loss is a good thing for our side, especially looking ahead to '08, because it demonstrates just how completely the far left has taken over the Democratic party. They're out in the open now...
Lamont is worse.
But in a way, a Lamont win is VERY good for the GOP and the death knell for the damned Dems.
