So on universal healthcare I'm not sure, but based on party preference and voter participation it looks like right-wing poor people are a minority. There's a linear relationship between voting and income and there's a clear party preference based on income as well.

Poor people usually don't vote, and when they do they usually don't vote to the Right. I guess I'm just assuming that translates into things like universal healthcare. I need to go to work so I'm out of time to find out for sure though lol
