I think maybe 1/2 of the U.S. is brainwashed and the other 1/2 isn't. To get brainwashed people have to watch TV and read books and newspapers that are all basicaly from the same source.
But the internet changes that up a lot cause the sources are from the whole planet. And school and immigration helps too cause you can see how different other people are and a lot of the cool ideas they have.
We don't even watch TV here. Everything we watch is on DVD's or online. And the only way to really get what's happening in the world is to look at different sources then decide what adds up. When I hear about something interesting then I check it out in the U.S. news, Российская газета, Al Jazeera, Le Monde, and other news sources.
If fewer people get brainwashed then maybe we can get people in Congress that aren't brainwashed. Maybe even have a law about NOT letting Altzheimers victims (like McCain) run the country.
