I doubt it. LA's Mayor Tom Bradley retired rather than run for (and lose) re-election after the LA riots. NYC's Mayor David Dinkins lost his re-election bid after the Crown Heights riots. Black political figures are expected to keep the racial peace. Race riots do not count in their favor.
I think you speak to a core issue about Obama and his administration. Conservatives fall into two general groups regarding this:
1. Obama is a complete incompetent and this whole administration is gonna end very, very badly, possibly taking the US down with it.
2. Obama is a master chess player, thinking a hundred moves ahead and all this stuff fits into his master plan.
I’m in group number one. I will add that if it turns out to be number two it means he is the Beast spoken of in Revelation, and God will get directly involved.
But I am in the first group until evidence convinces me otherwise.
