I know several people who voted for Obama.

 They are neither stupid or partisan. They are average people just trying to get by and working their tails off in the process. After a long hard days work, they relax in front of the TV. They may watch a sitcom which does a sympathetic story about a gay couple or a story slandering the Catholic Church. Then they might watch some news and see basically the same stories, now presented as “fact”. Then they go to bed. They simply do not have the time or energy to investigate issues for themselves, and so this becomes their reality, one in which the choice is between a humble grass roots liberal or a rich capitalist conservative.
