Great for RI (I had forgotten that Maine had legalized it). So we're up to 10 states now? I wonder when we'll get 20?
As far as Pennsylvania goes, I think it's a good way off - there is just far too much rural presence in our state government. The PA House is your typical rural southern-state kind of House. They rammed through a ridiculous "Year of the Bible" a year or two ago - the PA House is far-out conservative. So I think court is the best bet certainly in anything like the short term. Referendum right now would be doubtful. Stress right now. At least I'd be surprised if it would pass.
It's like they say: Philidelphia and Pittsburg with Alabama in the middle.
