How Can People Be So Weak-Minded as to Believe "Obama 2016"?

It's a movie I heard about from GodfatherPolitics, a movie in which the producer paints a picture of 'what the world will look like if Barack Obama gets re-elected President of the United States.' My browser was too slow to read past the first page of http://godfatherpolitics.com/6667/2016-what-will-america-look-like-if-obama-gets-re-elected/ ... though the first page told me a couple things: 1) deSouza (the producer) tells a believable tale because he quotes directly from Mr. Obama's writings & 2) political writers get on each other's good-side by agreeing with them. The blogger and the movie-producer seem to be overlooking one key fact: the President has no more power over people's behavior than a prophet has over the future he foretells. The reason why the President is "the most-powerful man in the world" is that his words are regarded as 'commands' when they are nothing more than 'probably-good suggestions.' How can we wake people up to the fact that the President is only powerful if people choose to follow his suggestions?
