The latest from Robert Novak:

While our seat-by-seat analysis shows Democrats winning the House by a four-seat margin, the overriding question is whether a "wave" will deliver a really big Democratic majority. That presumes an overwhelming sentiment that negates seat-by-seat analyses...

Our current count is that, if the elections were held today, Democrats would gain control of the House, with a pickup of 21 seats, but Republicans would kept the Senate while losing four seats.

Novak's full analysis here. Some interesting Novak nuggets: He predicts a "Likely Democratic" takeover in NM-01, a seat that's considered a toss-up by Cook, CQ, and Rothenberg. He also touts the RNC's "bimbo" ad as one of the reasons Republican Bob Corker may be "turning the corner" towards victory in the TN Senate race — even though the ad is getting taken off the air today.

Meanwhile, the National Journal's Chuck Todd today also updated his Senate rankings, with Ohio and Virgina each moving up one spot on the list of seats likely to change hands to 2nd and 7th respectively.
