Argall won re-election last year. He is not up till 2024 but Jake Corman on the other hand is up in 2022.
Here in PA we split our 50 state senators elections by having 25 of them every two years.
Odd numbered districts were up last year like Argall’s (29th) and even numbers like Corman’s (34th) are up next year.
I am well aware since I have lived in PA all my life.
