It probably doesn't get mentioned enough, but Joe Lieberman's independent Senate campaign is likely to have a serious impact on the Dems' chances of winning back the House. Connecticut has three incumbent Republicans (Nancy Johnson, Rob Simmons, and Chris Shays), all of whom are considered vulnerable this year against strong Dem challengers (Chris Murphy, Joe Courtney, and Diane Farrell).
If Lieberman is encouraging Republicans and other conservatives to go to the polls to support his candidacy, Dems are understandably worried that those same voters will back GOP House candidates, undercutting key opportunities that could help shift the balance of power on the Hill.
Lieberman has heard the argument and has a response.
