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.
