Connecticut poll
I am certain we will be getting polling updates on this nearly daily until November, but early on Lieberman has a lead and is polling better than his opponent.
Prior to any polling I figured he had a shot as an independent. It looks like he may be the one to beat.
I figure that if he stays up in the polls many dems will start to endorse him to look good when he wins, and that will pave the way to them bringing him back in the fold do that they aren't down a senator after November.
