Pennsylvania’s Senate race took an extra-nasty turn this week as Democrat John Fetterman flung a serious accusation at his Republican rival Dr. Mehmet Oz — that the celebrity heart surgeon is a fan of the Dallas Cowboys.

“Now that Dr. Oz is running for office, he *acts* like he’s a real Philly sports fan. But we all know he’s really a Cowboys fan,” Fetterman tweeted on Tuesday.
