I think people are quick to judge candidates based on race, religion, sex, and age is because it is easy to tell the difference. I mean if you don’t want a woman in the office its easy to discriminate because you obviously know the difference. When it comes to politics a large number of people have no idea what simple things like the GDP is or what it means when the FED contracts the supply of money. So they default to what they know and understand to base the opinion of a candidate.
