The Republican primary race for Pennsylvania’s open U.S. Senate seat is still too close to call as of Wednesday morning.

Dr. Mehmet Oz, who was endorsed by former President Donald Trump, and former Treasury Department official David McCormick both secured just over 31% with over 95% of votes tallied.

Conservative commentator Kathy Barnette is sitting around 24%, meaning the race is essentially between Oz and McCormick for the right to face Democrat John Fetterman in November’s general election.
