Celebrity surgeon Mehmet Oz is poised to shake up the Pennsylvania Senate race, bolstered by a vast personal fortune to invest in a 2022 campaign and enviable poll numbers that suggest the Republican would be an immediate front-runner.

Oz, 61, has not decided whether to pull the trigger on a bid for the seat being relinquished by retiring Republican Sen. Pat Toomey. But if the television personality runs, he is prepared to back the effort with millions of his own money and would begin a campaign for the GOP nomination with stratospheric ratings among key demographics, a source close to Oz revealed in an interview with the Washington Examiner.
