I think it will be California or maybe Hawaii. I doubt Maryland will trend more Democratic, in fact I expect it to become less Democratic over the next few decades (but obviously not by much and it wouldn't be enough to make it competitive at the presidential level).
Really? Do you see the Baltimore area giving out or something? To me, MD seems to fit well with what we are seeing in VA/NC/GA.
Yup. The DC-Baltimore corridor is actually getting more Democratic, which is a way bigger trend then whatever's happening with angry West Marylanders or in Delmarva.
