Thanks for your insight and you are correct, Like you I have roots in western PA and central PA and working experience in BW MD corridor and NORVA. NORVA was conservative when I was there. Montgomery and Baltimore County liberal. Frederick and west conservative. Pigeon holing rarely works.
Actually I meant I know because my roots are partly in western MD including the farm with the Mason-Dixon marker. I’ve been a native central MDer but heavily visited up there in the mountains.
