This idea that blacks will riot and burn if Romney wins is a myth.
If Romney wins a big part of the reason, will be that blacks and hispanics did not turn out and vote in the record numbers needed. There will be a lot of finger pointing in the black community, but no significant riots. Do not confuse the actions of criminals looking for freebies (which can happen anyday for any reason) for the community as a whole rioting, because of the election outcome. So if you see news footage of 25 or so young black people running thru and stealing everything out of a 7-Eleven somewhere in America, no need to load up your Car-15...they are not coming for you!! Lol.
While Obama's support is still incredibly strong in the black community, everyone understands that history has already been made and there is a greater concern for job creation at this point. My cousin works in Ohio as a minister and there is a lack of enthusiasm among that crowd for him as they see him having spent more time promoting things like gay marriage, rather than initiatives that would help with high unemployment that black people face. Now these people are not going to support Mitt Romney, but there will be no fury if he wins. The big problem that Obama faces is going to turn out among minorities and the young and if that fails to happen it cannot be blamed on white republicans.
Obama losing a very close election is not the same thing like him being taken out or something.
