HARRISBURG, Pa. (AP) – Vote counting in Pennsylvania’s Republican primary for U.S. Senate has dragged into a third day as Dr. Mehmet Oz and former hedge fund CEO David McCormick remain essentially tied with tens of thousands of ballots left to tally. Oz led McCormick by 1,240 votes as of midday Thursday. The race remains close enough to trigger Pennsylvania’s automatic recount law, and Oz’s margin has narrowed. Pennsylvania’s Department of State, which oversees elections, says there are about 51,000 mail-in and absentee ballots – 17,000 in the Republican primary – left to be counted. Oz and McCormick have said they believe victory is near.
