COLUMBUS, Ohio (AP) — Three-term Democratic U.S. Sen. Sherrod Brown of Ohio faces perhaps the toughest reelection challenge of his career Tuesday in the most expensive Senate race of the year as control of the chamber hangs in the balance.

Republican car dealer and blockchain entrepreneur Bernie Moreno defeated Senate Banking Chairman Sherrod Brown in Ohio, ousting the Democratic party’s most prominent populist and putting the GOP on course toward a Senate majority.

Sen. Sherrod Brown, the Democratic Party’s mainstay in the red state of Ohio, has been ousted from the Senate by MAGA Republican Bernie Moreno. Moreno’s win, which was called by the Associated Press at 11:27 p.m. EST, all but ensures Republicans will take control of the Senate.
