WASHINGTON (TND) — The GOP primary for the U. S. Senate seat in Pennsylvania is still too close to call, separated by less than half a point more than 24 hours after polls closed. Celebrity Dr. Mehmet Oz has 31. 3% of the vote while businessman Dave McCormick has 31. 1% and the state is still counting tens of thousands of mail-in ballots. If the margin is less than 0. 5% once all votes are counted, there will be an automatic recount, which could take weeks.
