I like this idea. I was going to complain that we'd see some of that same region-moving to try and gain an advantage, something that would be laughably easy in current times with smaller voter bases as it would be in the subregions, but then I saw the point where voters would have to move several weeks in advance, far ahead of the election shaping up.
I personally had thought a unicameral legislature would be better for efficiency purposes, and this is pretty damn near perfect.
I do feel somewhat left out since obviously y'all made this Labor-Federalist bipartisanship, but I support this plan nonetheless
