Democrats approve of Lieberman by only 50-46%. Republicans approve of him 65-33%.
I've gotta admit, the liberals have run an amazing campaign in Connecticut. A month ago, I would've never even dreamed the Lieberman would lose the primary, let alone being contested in the general election (rasmussen has a Lieberman-Lamont at a tie, and if the trend continues, Lamont will be the junior senator from Connecticut in January). Now why can't liberals be this effective against actual Republicans and in Presidential Elections?
Pay more attention, for example Montana.
