> knowing whether someone is a {Trump} supporter is pretty good at predicting the rest of their viewpoints. If instead of "is a supporter" you'd said "agrees with Trump's positions", then even Trump himself might not correlate very well :-). I don't see Trump as a very useful proxy for nuanced political viewpoints since he's a populist who tends to change positions. I think many serious conservatives only align with him on an issue by issue basis because position-wise Trump isn't very consistent on traditional conservative issues. I suspect someone being "a Trump supporter" is, at best, either a proxy for being dissatisfied with the political status quo or for having a strong one-issue alignment with one of a handful of culture war issues Trump campaigned heavily on. Similarly, alignment with the current Democratic or Republican political parties isn't the proxy barometer it once was. As judged by how they vote on close, consequential issues, both of the major parties have largely abandoned several of their traditional positions - although they still may pay lip service to them when campaigning. Personally, I don't meet nearly as many people in recent years who claim to be 'all-in' on all the positions of either major party (especially as judged by how that party votes when they have a super-majority).
