Poll: Joe Lieberman Sinking At Home As He Campaigns For McCain

According to a new Quinnipiac poll, as Joe Lieberman campaigns for McCain his approval rating at home is sinking:

Sen. Joseph Lieberman gets a 45 - 43 percent approval, down from 52 - 35 percent March 27 and his lowest score ever.

"Sen. Lieberman's approval rating has dropped below 50 percent for the first time in 14 years of polling, with nearly two-thirds of Democrats giving him low marks, probably because he is campaigning for Sen. John McCain," Dr. Schwartz said.

Lieberman recently argued that voters should choose John McCain because a terrorist attack would come early in the next presidency.
