Americans know so little about civics, will not keep up with current events but cannot miss Survivor, etc, etc.
They are ripe for the media and political party manipulation. They seldom know much about the candidates they vote for.
This is why pols put on such "shows" in DC. All about the 30 second sound bite which corresponds to the attention span of most Americans. And we are surprised at the idiots that get in office. Oh well.
