Bob Casey, David McCormick face off in 1st Pa. US Senate debate Thursday. Here’s what to look for.

With about one month before the election, incumbent Democratic Sen. Bob Casey faces GOP businessman Dave McCormick Thursday in their first debate.

Casey is seeking his fourth term.

This is McCormick’s second run for a U.S. Senate seat. He lost in the 2022 Republican primary to Mehmet Oz, who went on to lose to Democrat John Fetterman in the fall.
