On the House, I was just wrong. I predicted (in a comment thread somewhere else, and I don't remember where to link to it) that the Republicans would pick up 45 to 55 House seats. They rang up 65.
In the Senate I predicted here at KN@PPSTER that the Republicans would not take control of the Senate. I was right. I predicted that they would only pick up four Senate seats. I was wrong, but it remains to be seen how wrong. They've got a net pickup of at least five, with two races -- Washington and Alaska -- still in the air.
My prediction for Alaska was that incumbent Lisa Murkowski -- who is now an independent write-in rather than a Republican -- would win. At this time it looks like she has, but it will probably be weeks before the write-in votes are all verified.
In Washington, I predicted that Democrat Patty Murray would beat Republican Dino Rossi. That one is too close to call, but it looks like I was right.
I was wrong on two details, but they canceled each other out: I picked Republican Buck to beat Democrat Bennet in Colorado; Bennet won. I picked Democrat Giannoulas to beat Republican Kirk in Illinois. Kirk won. Republicans won in Pennsylvania and North Dakota as well -- races that for some reason weren't even on my radar.
So, I'd give myself an F on House predictions and, unless something changes in Alaska and Washington, a C- on the Senate.
