I am confused by that premise. How will blacks starting the race war turn into white sympathy and gen up votes for nobama?
Such race war will likely result in those who had some guilt inspired sympathy would be the first inline for attack by the blacks, simply due to opportunity.
Most likely any such race war would definatley not be symetrical, maybe their rout will rekindle blind liberal kinship?
It’s militant fringe groups in general, not just black militants. The idea is as society degenerates, people begin to call for a strong government (think fascistic) to control the chaos.
