Live results: Pennsylvania US Senate race still too close too call

It's been more than 24 hours since the presidential race was called for Trump in Pennsylvania, but the state remains embroiled in a tight U.S. Senate race between incumbent Bob Casey (D) and David McCormick (R). 

Casey has won his last three reelection bids since he won a U.S. Senate seat in Pennsylvania in 2006. McCormick has never held an elected office, but he built name recognition when he went head-to-head with Dr. Mehmet Oz for a republican Senate seat nomination two years ago.

On Wednesday, the Casey campaign said they were "confident" in their road to victory.

"There are more votes that need to be counted in areas like Philadelphia, and it’s important that every legal ballot will be counted," a campaign spokesperson told Jeff Cole. "When that happens we are confident the Senator will be re-elected."

As of Thursday morning, McCormick held a .4 percent lead - less than a 30,000-vote difference - with 98 percent of votes counted.

"McCormick is up 30,679 votes with more to come, as ruby red Cambria County is still outstanding. While votes continue to be counted, any way you slice it, Dave McCormick will be the next United States Senator from Pennsylvania," said Elizabeth Gregory, McCormick communications director.

Incumbent Bob Casey (D) and David McCormick (R) along with five other candidates are vying for Pennsylvania's U.S. Senate seat. Casey, whose website describes him as "a voice for middle-class families, workers, and seniors," has won his last three re-election bids since he first won a U.S. Senate seat in 2006.

Meanwhile, McCormick has never held a political office and lost the 2022 Pennsylvania Republican primary for U.S. Senate to Dr. Mehmet Oz, who ultimately lost to John Fetterman (D). Still, the Associated Press called McCormick's campaign "the strongest challenge to Casey in his three reelection bids."

McCormick, an ex-hedge fund CEO, earned an endorsement from former president Trump during his campaign. Casey, meanwhile, was endorsed by both Vice President Kamala Harris and Fetterman.
