You ever notice?
Bright, creative, educated people tend to be liberals. These are people who read, travel and are aware of other cultures, philosophies and people.
Dull, frightened anxious people tend to be Conservatives. Not as well educated, traveled or exposed to other cultures, philosophies or people. May have an education more slanted toward numbers than words. Tend to need God and guns to help quell their fears and built-in sense of inadequacy.
There's a reason for that.
