"These associations remained significant even once the researchers controlled for political party."

This seems to rule out the correlation coming from manual labor being associated with conservatism.

Evolutionary psychology is a collection of these "just-so" stories, they apparently don't have anything else to publish, and no one ~should~ take them seriously.
