Democrats win the Senate — by the slimmest margin possible Vox.com 1/6/2021 Ella Nilsen Winning a pair of January 5 Senate runoffs in Georgia, Democrats have regained control of the US Senate, but just barely. By capturing Georgia’s Senate seats — an impressive feat few political observers thought likely after the November election — Democrats have given themselves the barest of Senate majorities. They are technically split 50-50 with Republicans, with Vice President-elect Kamala Harris serving as the tie-breaker for simple majority votes. Importantly, though, it will be Democrat Chuck Schumer, not Republican Mitch McConnell, who will hold the title of majority leader.
