Jon Chait is right. Tonight was an excellent night for Democrats. We held the PA-12 (special election to fill John Murtha's seat) -- not too shabby, given that the district was the only one in the country to vote for Kerry in 2004 but McCain in 2008. Joe Sestak is, I think, a more formidable opponent for Pat Toomey in Pennsylvania. Bill Halter pushed Blanche Lincoln to a run-off, which I believe he'll win -- it's a push as to whether this helps or hurts (not so hot) Democratic chances to retain the seat (Halter isn't an incumbent, which is good, but he's also quite liberal for Arkansas), but in a coin-flip environment I'd prefer the more liberal of two options. Finally, the Kentucky race ended up exactly as one would want it, with AG Jack Conway pulling the Democratic nod to face Tea Partier Rand Paul -- by far the most favorable match-up possible in the Bluegrass State.
So yeah. Good night.
