John Fetterman has reportedly strengthened his lead over Mehmet Oz in the race for Pennsylvania’s U.S. Senate seat. A survey by a Trafalgar Group poll indicates Fetterman, the Democratic lieutenant governor, pulled in a little over 47 percent, while Oz, his Republican challenger, garnered just under 45 percent. Libertarian Erik Gerhardt received about three percent; four percent are unsure or undecided. Oz is running strong in three regions of the Commonwealth: Wilkes-Barre-Scranton, Harrisburg-Lancaster-York and Johnstown-Altoona-State College. Fetterman’s doing well in bigger metro areas.
