Could be a little too R-friendly, but for all the talk of Democrats having hit a "ceiling" in CA in 2016 and Democratic support being maxed out there now, I’d say that this state fits the description far better than CA.
I don’t think Maryland is the best candidate for maxed out Blue state either. Dems have plenty of room for growth in places like Frederick County and getting some Eastern Shore presence back, which they did in the 2018 Senate race and the MD-01 House race. New Jersey or Hawaii seem to fit that niche best.
