I actually don’t think that there will be riots when Obama loses - the electoral college has conditioned people to realize that it’s a game about states and there are more red than blues. In reality, my concern about riots is if he wins and then has an unfortunate incident occur.
White people avoid Black sections of large urban areas in any case. It is not safe there. Obama’s South Side of Chicago has outstripped Baghdad's casualty figures for about six months now. (Funny how no reporter ever asks him about this) Two or three killed and many more wounded every day. How will we know when they are rioting? They are rioting every day.
