The left has already shown their colors. Hitlery and Holder reinforced their colors this week. If the left loses, badly in particular, I expect rioting to commence in some areas. But I don't see the whole country going up. Big cities, specially the big liberal cities though may be burned to the ground. That seems to be their MO at least to this point.
I do think the left has go unhinged and have cost themselves votes by their actions. The economy is stronger over all than it's been in years. People like havin money to spend on stuff they need. IMO Blacks and Hispanics are seeing that and some are looking at the difference from a black leader and someone who does more than talk a good game.
