Democrats retained control of the U.S. Senate on Tuesday night, taking over hotly contested Republican seats in Massachusetts and Indiana while holding on to most of the states they already had, including Wisconsin and Virginia, according to projections.
The most significant turnover victory for Republicans came in Nebraska, where conservative candidate Deb Fischer was the projected winner in a race for the seat of retiring Democrat Ben Nelson.
Overall, the balance of power appeared poised to remain unchanged in Congress.
That likely means more partisan gridlock, as Republicans were projected to remain firmly in control of the House of Representatives.
While the Senate did not change hands, it could wind up as a more polarized body, with fewer moderates in both parties.
