The ancient attempt of a 1d embedding of political ideologies is doomed to fail, however anyone tries. It started out in revolutionary France in 1789 to distinguish between the supporters of the king (conservatives, on the right) and supporters of the revolution (revolutionaries, on the left). It was good enough for that, but it's not for very much else.

The most sensible minimal extension (to 2d) that I know of is to distinguish between how much you value personal freedom on one axis and economic freedom on the other. That still leaves out a lot, but is the best indicator of which side you'll likely to end up on regarding most political contentions, given the simplicity of the model.

There are actually two popular models of that kind, the Nolan Chart (example quiz [1], your spectrum is the vertical axis) and the Political Compass (example quiz [2], your spectrum is the secondary diagonal).
