Over at the Intrade predition market, the price for GOP control of the house has plunged to 21.3 over the weekend. I think this probably means the uncertainty in the polling data is going away as people are running out of time to change their minds. The smart money (55.1) seems to be on a Democratic House and a Republican Senate.
I don’t know how smart Intrade’s bidders are, but they know a lot more than I do, so that’s my prediction too.
I’m also going to go out on a limb and predict that no Illinois Senators will lose their office in this election.
