I'm from Massachusetts, though no longer living there. My strong suspicion is that this reads, "Let's try a bunch of things that might work. Then the next time a Massachusetts Democrat wants to run for president and talk about universal health coverage, they can point to the things that worked." In other words, it's a lab. I might have something to say about trying all your independent variables at the same time, but... It's better to try something. Massachusetts appears to have designated itself the Official Social Experiment State, and I'm proud of 'em.
