AMERICAblog: What yesterday's victory means
AMERICAblog: John's summary is illuminating and helpful: "I don't think the election was a victory for conservative Democrats or liberal Democrats. It was a victory for Democrats across the board, and a repudiation of Republicans and conservativism.
Conservative Dems, like Bob Casey in PA, won. Conservative Dems like Harold Ford in TN lost. Liberal Dems like Sherrod Brown in OH won. Liberal Dems like Ned Lamont in CT lost. There was no absolute pattern, in my view, as to liberal Dems winning or losing or conservative Dems winning or losing. Democrats ran a variety of candidates, from left to right, and some won and some didn't. And that's the way it should be. I don't think you can win by only running conservative candidates (good luck in SF), or only running liberal candidates (good luck in much of the south). You need to run a bit of a rainbow, and that makes sense - America isn't left or right, at least not exclusively."
It's an excellent post--go read the whole thing.
