As an American, I think about this graph *way* too often:  Basically, yeah. Ideally, as public support rises, the pass rate would also rise. And inversely, as support drops, the pass rate would also drop. That flat ~30% pass rate *regardless of public support* means that the bottom 90% literally isn’t represented at all. Their needs and wishes literally are not factored into the bill’s chances of passing ***at all***. Meanwhile, the wealthy have an *extreme* amount of influence on whether or not a bill will pass.
