Political science doesn’t place everything onto a left-right single dimensional line. If you think it does you need to spend some more time actually reading.

Additionally, political science has many subfields and the ones that are closely related to political beliefs are subject to the same replication crisis as the other fields of social psychology (i.e. lots of junk science). So any of that stuff that generalizes 1 dimensional outcomes to entire lifestyles and views is likely complete trash.
