Intrade is predicting that the GOP will win 8 seats from the Dems, lose 1 seat to an independent, and the Dems will pick up 0 seats. If the pediction market is correct, the Democrats will have 49 seats, the Republicans 48 seats, and 3 Independents. Two of the Independents already caucus with the Democrats. The other Independent would be Murkowski in Alaska, who presumably would caucus with the Republicans. Republicans are expected to win the following states with Democrat incumbents - AR CO IL IN NV ND PA WI.
