The political spectrum isn't left to right, despite some places seeming that way. The political spectrum is both progressive to conservative and libertarian to authoritarian. Although that's a lie and it isn't as simple as that either, because it doesn't work for differentiating green conservatives from regular conservatives, for example.
I’d argue the opposite- most people don’t think of politics in terms of goals, philosophy, or policy but in terms of group identity. In that sense, politics is the USA is effectively binary rather than one dimensional.
If you’re going to talk about something like philosophical values, you could have almost infinite dimensions, but you’d find it impossible to place most actual voters anywhere because the dimensions will represent things they have no opinion on and have never thought about.
Green conservatives are still talking about climate change as their main issue. Regular conservatives just want these fucking fascists deposed, in prison, and their deplorable enablers back to being ashamed ^_^
