This is hands down the best breakdown of the American political impulse ever — clear and simple. Since, at least subconsciously, every human being goes about life as if he or she is the center of the universe all these political divisions and subdivisions must run though a combination of ego and intellect.

That is to say that with ego (the lynchpin of the survival mechanism) as the foundation of the mind, it being either strongly enhanced by intellect (sophisticated broadmindedness) or not, where instead a kind of narrow minded fundamentalism runs free, driven mostly by tribal impulse, this combination allows folks to settle into your afore mentioned political groupings.
