The U.S. Senate is where the real battle is today.
Democrats and allied independents hold 59 Senate seats. Republicans hold 41 seats.
The GOP is expected to retain open seats that Republicans now hold in Alaska, Florida, Kentucky, Missouri, New Hampshire and Ohio.
Republicans also are expected to pick up Democratic seats in Arkansas, where Tea Party-based John Boozman should unseat incumbent Blanche Lincoln; Wisconsin, where Ron Johnson is favored to unseat Russ Feingold; and Indiana and North Dakota, where Democratic incumbents are retiring.
Taking that into account and including Senate seats not on the ballot today Democrats will have 48 seats and Republicans will have 43, leaving control of the Senate to be decided in seven races.
