Democratic Lieutenant Governor John Fetterman will face Republican Dr. Mehmet Oz in the first and only debate of the potentially crucial U.S. Senate race in Pennsylvania tonight at 8pm. The candidates will meet in Harrisburg and the Fetterman campaign appeared to tamp down expectations in a memo to reporters on Monday that referred to the fact the Democrat is still recovering from a stroke he suffered in May. Fetterman will use a closed captioning system onstage to read moderators’ questions and the campaign noted he has “ongoing auditory processing challenges.” The debate is likely to be contentious, with Fetterman’s health one potential topic as the Oz campaign has questioned his ability to serve following his stroke.
