John Fetterman suffered days before winning the Democratic Senate nomination in May. The stroke added a new wrinkle to a race that could determine which party takes control of the 50-50 U.S. Senate. The Oz campaign is clearly hoping that perception will hurt Fetterman. In one egregious example, Oz issued a list of “concessions” for their debate Tuesday night that many see as mocking. Benjamin Abella, a professor of emergency medicine at the University of Pennsylvania, criticized the Oz campaign for shaming a stroke survivor.
