After months of campaigning and conducting crowded rallies, Pennsylvania Republicans still don’t have a primary election winner for the United States Senate. There are seven candidates fighting it out for one Senate nomination.

The delayed election result has been caused by a tight race between celebrity heart surgeon Mehmet Oz and former hedge fund manager David McCormick. Mehmet Oz has been endorsed by former President Donald Trump.

Mehmet Oz secured 31.3% of the votes on Tuesday while David McCormick closed in with 31.1%, according to the live polling.

According to Pennsylvania’s state electoral law, if two candidates have a margin that is lower than 0.5%, a recount needs to be triggered to accurately determine the choice of the voters. With just a few hundred votes separating Oz and McCormick, the result may not be clear for several days.

Other candidates on the Republican ballot for the US Senate seat include Kathy Barnette (24.8%), Carla Sands (5.4%), Jeff Bartos (4.9%), Sean Gale (1.5%) and George Bochetto (1.0%).

The Democratic race for Pennsylvania’s Senate seat was much less crowded and had an easy winner. Only four candidates participated in the elections and John Fetterman secured more than 59% of the votes on Tuesday.

Fetterman was followed by Democratic candidates like Conor Lamb (26.4%), Malcolm Kenyatta (10.3%) and Alex Khalil (4.3%), according to the New York Times live poll.

Pennsylvania’s Republicans made a definitive choice for the governor nominee on Tuesday and picked Doug Mastriano, a far-right candidate who previously served in the US armed forces.

Tuesday marked the busiest night of the nascent primary season, with contests also being waged in North Carolina, Kentucky, Oregon and Idaho. Both parties are choosing candidates to enter the fall general election, when control of Congress, governor’s mansions and key elections posts are up for grabs.
