May be wrong on this, but I think this election was just to fill the seat till November when the same 2 candidates will run again.
Any clarifications/correction appreciated.
If true the news media likes to leave out these little clarifiers as there is no guarantee that he will win again with the margin being so slim and the potential it could get even tighter or overturned.
PA is in the process of redistricting. That district, as it exists today, is expected to change significantly. At this point, it’s hard to know who will be running and where.
