Dr. Oz will run for Pennsylvania’s open Senate seat as a Republican

Celebrity doctor Mehmet Oz will run for Senate as a Republican in Pennsylvania next year, adding intrigue to one of the races that will determine control of the chamber.

The 61-year-old host of “The Dr. Oz Show” will enter a crowded swing-state race where no clear frontrunner has emerged on the GOP side. Oz, who has never held elected office, will try to leverage his name recognition and wealth in the bid to replace retiring Republican Sen. Pat Toomey.
