ELECTION 2014: Monitor the balance of power in Congress, governor's races

WASHINGTON (AP) — Right now, Democrats have a 53-45 majority in the Senate, and they usually have the support of two independents. But on Tuesday, November 4th, 36 seats are being contested. Republicans need to gain six seats to win back the Senate majority they lost in 2006, and their odds are good.

In the Republican-controlled House, all 435 seats are up for grabs, but the GOP is expected to stay in control.
