The worst gun laws in MA will get repealed right around the time pigs (other than MA politicians, and frankly calling some MA politicians pigs is insulting to pigs. ) and start making regularly scheduled flights at Logan airport.
Outside of the current AG's race (and even if Jim wins, he still has VERY limited influence) my prediction is absolutely nothing will happen if it doesn't involve a court battle at this point. Some laws could change as an indirect result of Heller/MacDonald..... but that is likely even going to take years by itself.
The elemental problem in MA is there are too many moonbats, and as time goes on, this gets worse. A lot of people will go "but but, there are a lot of independent voters in MA" and what "independent" usually means, is "usually will vote for a democrat or a worthless RINO".
It also doesn't help that MA house and senate pretty much have endlessly corrupt, rotten to the core, leadership, either. In between Chick-Fil-A and a couple of speakers that have gotten hit with federal indictments, we're racking up a score on political corruption in MA, especially if you start counting the massive garbage dump sized amounts of soft corruption that happens every day in the state. This obviously has a drastic effect on what bills get floated, etc. Ironically enough we've also benefited from legislative sloth as well. Uhauls OGAM proposal failed because the legislators, and the legislative leadership, hate him. They might all be moonbats/statists, but that's not enough glue to get them on the same page.
