Why do people vote the way they do?

[patoadam]

I would like to know why people hold the political opinions they do and vote the way they do. (Translation: Why doesn't everyone agree with my obviously correct political opinions and vote the way I do?) I have listed some popular explanations below. I should mention that the brief summaries I give do not do justice to the writers' nuanced arguments.

How can I tell which hypotheses are correct? Or are they all correct, as in the parable of the blind men and the elephant? Or is it impossible to answer "why" questions, because correlation does not imply causation? Can you suggest other theories I'm not familiar with?

Conservatives are authoritarian; liberals aren't.
Mark J. Hetherington and Jonathan D. Weiler, Authoritarianism and Polarization in American Politics

Conservatives come from strict-father families; liberals come from nurturant-parent families.
George Lakoff, The Political Mind and Don't Think of an Elephant

Conservative are more easily squicked than liberals.
See this article

Morality is based on five principles: caring for others, fairness/reciprocity, group loyalty, respect for authority, and purity/sanctity. Liberals base their beliefs on the first two principles; conservatives base their beliefs on all five principles.
Jonathan Haidt, as described at moralfoundations.org

Political opinions are based on emotion, not reasoning.
The Political Brain, by Drew Westen

Blue-collar workers, who used to be liberal for economic reasons, have become increasingly conservative because conservative politicians have increasingly emphasized social issues such as abortion and gay marriage.

I attribute it to the fact that 50% of the population is below average. I know it's frustrating, but it will always be true, and there's nothing us above-average people can do about it
