Well we already know that if you are high in conscientiousness in the big 5 personality traits, you are likely to be conservative, and Openness predicts for more left leaning views, this is seems to be before political views are established.

I'd say that it's definitely likely we see the world vastly differently, and that changes our political opinions for sure. Idk if it's a actual biological marker, like different part of the brain develops differently, that seems odd.

I'm actually deeply interested in what enables us to perceive the world. And it seems like we see patterns, which enables us to see stories & objects, which enables us to assume things as good/bad. These patterns and subsequent stories we see, change what we look at. For instance, we assume ppl in the store won't kill us. Or we see the pattern of faces in abstract designs (like the famous martion face on mars). This deeply influences everything about how we perceive the world, so we might be extremely sympathetic to the poor, or maybe we look at the world more rationally. Experiences, culture and so on all help shape this world view, or what patterns we see as relavent, because ofcourse their are infinite amount of patterns to perceive. So it stands to reason that these will significantly have an effect on our political stances.
