Despite having apparently thrown away Delaware, Republicans are poised to retake the Senate. According to the latest Rasmussen polls, Republicans have the lead in Democrat-held North Dakota (+43), Arkansas (+18), Indiana (+16), Wisconsin (+12), Pennsylvania (+9), West Virginia (+6), Colorado (+5), Illinois (+4), Nevada (+4), and Washington (+3). GOP-held seats that were thought to be at risk now look safe: Florida (+25), Alaska (+15), Kentucky (+11), and New Hampshire (+7). If these results hold true, Republicans will pick up ten seats, just enough to put them in control of the chamber.
Also, the winners in West Virginia and Illinois would be seated immediately, which could make a difference in a mad duck session.
UPDATE: The GOP prices on Intrade: North Dakota (97), Arkansas (97), Indiana (95), Wisconsin (88), Florida (86.5), New Hampshire (86.5), Pennsylvania (86.5), Kentucky (84.9), Colorado (77), Alaska (75), West Virginia (70), Nevada (55.5), Illinois (53), Washington (50).
