I can make most of these now, because races don't change in the last few days.
That'd be 51-48 Democrats. The one race I have yet to pick is Colorado, but I'm leaning Republican. Alaska will be one of the two Republicans. I'm leaning Miller, but I reserve the right to change that one. Don't take this prediction as contradicting my post yesterday. I'm picking Boxer by the slimmest of margins and I know my California friends are going to do a big GOTV so I'll be proven wrong.
