Democratic Senator Raphael Warnock has defeated Republican challenger Herschel Walker in a run-off vote in Georgia. It was the final Senate seat left undecided from the 2022 midterms. While the Democrats already held the majority, Warnock's victory now gives the party an outright, 51-seat hold on the Senate. It's also a symbolic win for the party, since Warnock beat a candidate who was handpicked by Donald Trump.
