I think it's true: your abilities and personality determine how you vote. You may be hardwired to be more conservative or more liberal no matter which party you're in, but nature's secret is that those attributes reflect the kind of role in which you're comfortable.
If you've got true leadership potential, meaning that you can go into an unknown situation and figure out a strategy and see it to completion despite unexpected twists and turns, you'll think like a historian when it comes to politics.
If you're a hard working, clear-thinking person, you'll do your best to defend society and always be from the Don't Fix It If It Ain't Broke camp.
But on the other hand if you can't stop spending your money and time on distractions, and therefore are always beneath the wheel, you're going to get defensive and join the It's Not My Fault horde, and want handouts, special permissions, exceptions, etc. on a constant basis because you'll see yourself as the perennial victim.
I bet this applies to music, too, but not musical genre per se (although all nu-metal fans are drones).
