The whole JFK Jr thing is what's called "nut picking". You find some deranged element on the fringes and attribute their ideas to the whole of the group. The difference between the two parties is that you don't need to nutpick the democrats ,because their crazies are part of the mainstream.
(And before you say they aren't crazy here are some things they believe;
Jewish money controls the world,
Poor people would be better off if the police didn't protect them - only the rich should get protection from private police,
The people of the earth have sinned by polluting and the apocalypse is coming because of that sin. The only way to avert the apocalypse is by letting the government control the economy and every aspect of your life.)
