I think in this case the demographic split actually is correlated to the merits. As in, if you’re in a dense city, you’re probably more pro-rail, because you’ll be the one actually using that rail. If you’re in a culdesac suburb or even further from the city, you’re likely to not be pro-rail because you won’t be using it. You could call that tribal, or you could just call it “voting for your interests”. It feels slightly different from the tribal issues I see more frequently (policing, healthcare, schooling), but maybe I’m fooling myself.
