Republicans have officially retained control of the U.S. Senate.

It comes as Missouri Republican Roy Blunt and Alaska’s Lisa Murkowski won their two races in Tuesday’s election.

Republicans have a 51-47 edge in the Senate. Two races remain outstanding: In Louisiana, the seat will head to a runoff election next month. And in New Hampshire, Democrat Maggie Hassan and Republican Kelly Ayotte were locked in a too-close-to-call race.
