Ideological spectra don't really make much sense once things get multidimensional.
I wouldn't go that far. The electromagnetic spectrum still makes sense even though light waves differ in more ways than just frequency. And the left-right axis is still meaningful even though there're extra dimensions of political variation, although one has to think carefully about operationalizing the left-right axis, and remember that it explains only, say, 40% of variance in political belief, rather than 100%.
