Republicans have regained control of the House but failed to overtake Democrats in the Senate. With thirteen races yet to be called, Republicans gained fifty-nine House seats, the party’s largest win in congressional elections in more than a century. Despite losing six seats in the Senate, analysts expect Democrats to maintain control of the chamber with two key races yet to be called. In Colorado, Democratic Senator Michael Bennet and Republican Ken Buck are within a few thousand votes of each other with provisional and write-in ballots still to be counted. And in Washington, incumbent Democratic Senator Patty Murray is neck and neck with Republican challenger Dino Rossi.
