US people aren't any more stupid than any other people in the world. The biggest problem of the US (the majority, since there are a few true comrades there as well) is that you expect every four years a savior will fall from the heavens and solve all your problems without you having to move your asses.

It's your job as a socialist to do something. If you have nothing better to do, read theory. If you know theory, then agitate. If people are agitated, then demonstrate.
