Just a day before the election day, the control of the U.S. Senate hangs in the balance. Ten key states are up for grabs. The polls in most of those key races are too close to call.
Republicans only need to pick up six seats to gain control of the Senate. And according to recent polls, three are likely to be in their win column.
Republicans have history on their side, since FDR was in the White House, the president's party has lost an average of 6 Senate seats in the president's sixth year in the White House.
Despite all the talk of Democrats versus Republicans, it is third-party candidates that could make all the difference on election night.
In Kansas, Democrats could actually steal a seat for the GOP. Independent candidate Greg Orman is in a statistical dead heat with the Republican incumbent Senator Pat Roberts.
Jim Sciutto is in Kansas City with the latest.
