Nearly as important as the presidential election are the races that could determine the control of the U.S. Senate.
Chris Matthews broke down the states with potential game-changing races on Friday night’s Hardball.
There are six Democratic seats that could go Republican, including Montana, North Dakota, Nebraska, Wisconsin, Virginia and Connecticut.
There are also five Republican seats that could go Democratic, including Nevada, Arizona, Indiana, Massachusetts and Maine.
Democrats maintain a narrow 53-47 majority in the Senate, and heading into November, many analysts believed the GOP had a strong shot of winning the small handful of seats necessary to flip control of the upper chamber, particularly because Democrats were defending some two dozen seats to the GOP's 10. However, the conventional wisdom has shifted, and now the Democrats are favored to retain the Senate.
The non-partisan Cook Political Report said Friday that the chances of Republicans taking control of the Senate is slated at 40% to 45%.
