Unfortunately, that works against the idea of MD flipping. Those who see the light and have the means are leaving. The wife and I discuss leaving a lot, but we just had a baby so we're stuck for a few years. These ex-Marylanders coming to PA will vote Republican, so at least they'll help PA turn.
It's possible the way momentum is going that MD is interesting, but I'd bet on OR or NJ falling before we did.
