Republicans ousted three-term Sen. Sherrod Brown (D-OH) in Ohio on Tuesday night, likely cementing their control of the Senate for the first time in almost four years.
Well over $400 million were dedicated to the Ohio race, the most for any Senate seat in U.S. history. The race alone had the power to tip the balance of power in Washington, where Democrats hold a one-seat Senate majority.
Brown had a reasonable shot of keeping Ohio in Democratic hands. As the last remaining statewide Democrat, he was among a handful of incumbents whose race was rated a toss-up.
But he failed to get enough GOP votes from businessman Bernie Moreno, the Republican nominee who has aligned himself closely with former President Donald Trump.
