Democrat Annie Andrews has won South Carolina’s U.S. Senate race, defeating Republican Sen. Darline Graham, according to a projection by the Associated Press. AP called the race at 10:50 p.m. ET on Tuesday.

It is one of the biggest upsets of the night. South Carolina is a strongly Republican state that President Donald Trump won by about 18 points two years ago. Andrews will be the first Democrat to win a Senate election in the state since 1998, and the first woman elected to the Senate from South Carolina.

The seat was held for years by Republican Sen. Lindsey Graham, who died in July. Gov. Henry McMaster appointed Graham’s sister, Darline Graham, to fill the seat, and she ran to keep it with Trump’s backing.

As of about 11:45 p.m. ET, Andrews had 1,033,282 votes (51%) to Graham’s 947,521 (47%), with nearly every precinct reporting. The numbers are unofficial. No result is final until the state certifies it.

The win is a pickup for Democrats in the fight for the Senate. Republicans went into the night holding the chamber 53-47, and Democrats needed a net gain of four seats to take control. AP has not called control of the Senate.
