The time for voting has begun, and the Senate races in 2008 appear to be a mixed bag. Of the 31 races this year, the Intrade 2008 Senate race markets predict Republicans should win 14 races, while the Democrats are predicted to win in 19 states. The races in Georgia and Minnesota are still too close to call. Finally, Intrade traders predict Libby Dole will lose her Senate seat in North Carolina.
