they just are totally lost and seem to not have a brain
When watching 0bama speeches, I notice how his worshipers frequently applaud and cheer before he even completes his thought or sentence. They are riding an emotional tide rather than assessing the content of his statements. It's frightening.
It's called a "Cult of Personality." There are a few historical precedents, none of which ended well. In the case of Stalin, at meetings and speeches people became afraid to be the first ones to stop applauding him. Eventually they installed a light (actually colored lights which told the audience when applause was allowed and when it had to stop) at the podium which Stalin could turn off when he felt the applause could end and everybody stopped together.
