The key to American politics is that somewhere around 40% of the voting population are not too bright and not too educated. They have a pretty basic view of the World around them, that isn't necessarily reality based. Their political leaders are people like Sarah Palin, Rick Perry and the Dicks Armey and Cheney. They really like watching "Dancing With The Stars". It could be worse. In a lot of places it's 80 or 90% of the population that are ignorant dimwits. Actual reality based societies are limited to relatively few countries where the majority strongly value education and rational thought. I'm not that well traveled and could easily be wrong. There may not be any reality based societies. America may be about as good as it gets.
The forces of reactionary politics in America only need to come up with a little more than 10% of voters who are willing to humor the dimwitted 40% along and they can control the country. It's not that hard and may not be for quite a long time.
It would be nice to think that America is a country that is at least on a path to becoming a country of reality based, rational thought. I don't think it's true. If anything, people here are getting stupider all the time. Current demographics of immigration are not helping the situation. Bummer, Dude.
