A Georgia elections official said early Wednesday that it is “safe to say” the contest between Sen. Raphael Warnock (D-Ga.) and Republican challenger Herschel Walker is headed to a runoff election.

The development came after John Fetterman clinched a key victory for Democrats with a projected win in the Pennsylvania Senate race.

Fetterman’s win comes on top of a series of Democratic victories in key House and Senate races that are blunting GOP hopes for a titanic red wave in the midterm elections.

Sen. Maggie Hassan (D-N.H.) is projected to win reelection in a race seen as critical to Democrats’ hopes of holding the Senate, while Rep. Abigail Spanberger (D-Va.), one of the most vulnerable Democrats in the House, won a race seen as a bellwether.
