A book I have on this and recommend is "Our Political Nature: The Evolutionary Origins of What Divides Us." A number of good ones apparently came out around the same (2013) and of course others after, and this is neither the first or last word. But it offers a survey of what had been learned on this topic from various scientific disciplines, including neuroscience and genetics, and from a global viewpoint while addressing American politics.
Publishing on this topic for lay readers has been somewhat quashed since then as conservatives tend not to like what they're reading, but any search on it (personality, genetics, political, etc.) will turn up some things. Including such quirky findings as a study that MRI scanning of the brain could predict political orientation 83% of the time. "Scans show that liberals and conservatives use different parts of the brain when they take risks, helping to pinpoint the political party a person prefers." https://www.smithsonianmag.com/science-nature/study-predicts-political-beliefs-with-83-percent-accuracy-17536124/ According to something else I read, a quick glance at the MRI scans of a fair number of people can be as accurate, like looking at a pitcher's arms and knowing if he's a right or left thrower. It's because we tend to process information in different orders and exercise different parts of the brain a bit more.
Have fun. And for all the general conservative reaction to it, learning how and why we naturally hold the beliefs we do helps generate respect and empathy also.
