Swing Voters Will Rule in a Split Senate

Now that Democrat Raphael Warnock has won a U.S. Senate seat in Tuesday’s Georgia runoffs, with Democrat Jon Ossoff close to gaining the state’s other seat, the balance of power in the chamber tilts toward its most conservative Democrats, including Joe Manchin of West Virginia, Kyrsten Sinema of Arizona, and Jon Tester of Montana.

President-elect Joe Biden will need each of their votes—just as President Trump needed the votes of the least conservative Republicans in the Senate, Lisa Murkowski of Alaska and Susan Collins of Maine.
