A very interesting analysis. I've said that whether you are red or blue has to do with whether you are more afraid of the communists or the fundamentalists. Americans intuitively understand that the structure of their political system is the reason that it doesn't seem to reflect their interests. This comment takes that a little deeper.

I agree with his comment about the blogosphere. Its not a conversation. Its not a dialog. Its a million soap boxes. The popular ones tend to be the most polar because they are the most emotionally charged. The blogosphere, as it currently exists, is part of the problem. Its a check on the mass media, but it will be nothing more unless it can provide discourse.
