Too Close to Call: Control of Senate Hinges on Races in Wisconsin, Georgia, Arizona & Nevada

The balance of power in Congress is still up in the air after Democratic candidates outperformed expectations in much of the country in Tuesday's midterm elections. Control of the Senate now rests on four states: Wisconsin, Georgia, Arizona and Nevada. We speak with The Nation's John Nichols, who says Democratic Senate candidate Lieutenant Governor Mandela Barnes could still close the gap with Republican incumbent Ron Johnson in Wisconsin, who now has the advantage. He also says that while Republicans look favored to win the Senate seat in Nevada, the race has ended up closer than expected. Nevada can surprise you at the end," says Nichols.
