"What Happens After Lieberman Loses?"

Stuart Rothenberg provides talking points to bash the netroots:

Lamont’s general election numbers would immediately spike and Lieberman’s would drop, and the Senator’s prospects for victory in November would be uncertain.

Some Democrats fear that a three-way contest could encourage Republicans to find a way to force their nominee out of the race and replace him with a much more serious Senate candidate. But a Lamont victory would not seriously threaten the Democrats’ hold on that seat unless the Republicans were to find a stronger nominee.

Lamont’s victory, however, would not be without its downside for Democrats, since it would only embolden the crazies in the party, a consideration not lost on other Democratic elected officials and strategists.

Lieberman’s defeat is likely to add to the partisanship and bitterness that divides the country and Capitol Hill, and to generate more media attention to grassroots bomb-throwers who, down the road, are likely to make the party less appealing to swing voters and moderates.
