Don't quite understand why this discussion becomes a comparison between Obama, Bush, Clinton etc. The issue is the President in office today. He is the only one responsible right now to bring the Country together and he is doing the opposite. In my experience it is the first time in decades that a President has used the rhetoric of devicevness so effectively to keep the attention away from his limited understanding of the issues and the lack of his accomplishments. He emboldens the racist element that has always existed in the US (hence the hatred for Obama shortly after taking office) and unfortunately lowered the bar in public discourse and this has seeped into Canada as well. It is now fashionable to blame others for one's problems except of course if you're a visible minority and don't want to get shot by the police while doing nothing illegal. People who do not understand the disadvantage of being black in the US today have not studied their history and it's implications today.
