I haven't been doing much on the American congressional elections. Not much to say- it's going to be a bloodbath of biblical proportions. For the skinny, you should already know to go Here.
One thing I WILL say, though: this election worries me, because the Dems aren't going to win for anything they've done, really. There is no "contract with America" this time. There's no consistent message. There's just "we ain't Republicans", with a Republican party bad enough that that actually WORKS. Foley was a gift (as well as a tragedy) but that doesn't have anything to do with the Democrats.
We still don't really know what a Democratic Congress will actually DO.
