There are seven toss-ups at the moment, six of them Democratic: Joe Lieberman (D-CT), Claire McCaskill (D-MO), Jon Tester (D-MT), Ben Nelson (D-NE), John Ensign (R-NV), Sherrod Brown (D-OH), and Jim Webb (D-VA). All seven are either in the “very vulnerable” or “vulnerable” categories.
There are eight seats currently leaning to one or the other party. Six are Democratic and two are Republican. Of the eight, the seat of Scott Brown (R-MA) may be the most endangered, initially—although we believe some are underestimating his ability to win a full term despite the state’s heavily Democratic tilt.
The remaining 18 seats are “likely” or “solid” for the eleven Democrats and seven Republicans who occupy them.
