I live in the mountains in ☭california. I know 3 liberals up here, they keep their mouths closed as they are far from a majority on this hill. The liberal problem seems to be localized in the high population density cities.
My theory is that the air is still and full of smog in the cities. As I have COPD I know when I have a flare up my thinking abilities are impeded. The smog and still air cause a lack of oxygen in the cities and the possibilities of logical thinking or logical progression are minute at best. If we can figure out a way to provide the cities with good clean oxygen rich air there would be no more liberals.
