The people who support Obama fall into three camps.
The first camp knows nothing. They are hip hop fans, mall rats, no nothings and party going club kids. They see the movie Hancock or I am Legend and think Barack Obama will save the day like in the movies. They respond to him because he talks their lingo and says all the right things on the Colbert Report or Jimmy Kimmel Show. Actors, musicians and college kids fall into this group.
Then there's the second group. They are outright America haters, communists and socialists, diversity obsessed liberals, environmentalists, liberal professors and everything in between. They see "Change" as the American version of what happened in Venezuela, Bolivia, China or Vietnam. They understand Obama's code words to mean that he will change America in ways we have never seen. Not only do they think Obama is a JFK but they think he is better than all white presidents put together and all men throughout history. Obama has become the secularist messiah and Bush is the devil. Obama has come to save us from the Republican Satan. They see every pet liberal issue being pushed as far as it can go and America changing permanently into a pseudo Marxist utopia that will be Marxism and Maoism realized for the 21st century.
The third group is the scariest. They are Muslims who know who Obama is from his upbringing. They are blacks who will say, "this country is ours now!" They are the Mexican radicals who say, "We never crossed the border, the border crossed us!" They see Obama taking on and destroying Israel, whites, and redistributing the wealth to minorities and diverting taxes to trusted groups and new government positions. They hate this country 100% and see Obama as the quickest way to an end.
