You probably should never visit Western Maryland, then.
I have many times. I lived 36 years in Fairfax County. Yes, there are Rep areas of MD just like there are in CA.
MD house of Delegates--99 Dems to 42 Reps
MD state Senate--32 Dems to 15 Reps
MD Congressional Delegation: 2 Dem Senators; House members: 7 Dem, 1 Rep
MD is a solid blue state.
