And furthermore, there is much less of a chance for the Dems to regain control of the Senate, since Lieberman is now an Independent.
I would expect Lieberman would continue to caucus with the Democrats, even though he is running as an Independent. Jumpin' Jim Jeffords, for whom I am screen-named, after a fashion, is also an Independent, but he caucuses with the Democrats.
The thing is, in Primaries, you vote for the guy you want. In General Elections, you vote against the guy you don't want. We don't want Lamont, so you vote for the guy who is better than Lamont and has a chance to beat him. If the Republican candidate was not polling in the single digits, I would be enthusiastic about picking up the seat. But only one man can beat Ned Lamont, and that man is Joe Lieberman. That is why he has so much Joe-mentum going into November.
Besides, and honest old-school Liberal is not such a bad thing to have around, when compared to the collection of Moonbat Idiots who pass for the Democrat Party today.
