People still continuously vote for democrat because they are voting for what they think the democrat ideal is, not what it currently is (reality).
Look at all of the people who voted for Obama. They heard him talk and it sounded "about right" for what they think is liberality and democratic. But if they actually listened to his words and the context they were used in they probably would have thought much differently about it. He pretty much advertised cultural marxism in every way but that's not what people who believe in the democratic ideal actually heard. It flew right over their heads. Many refuse to admit it to this very day that they were hoodwinked.
