The short answer: nothing. Blacks usually vote 90% democrat in national elections, and they voted 95% for obama, the most leftwing and now clearly the worst president in US history. Yet when the GOP is in power, it dutifully goes about serving what blacks perceive as their interests. Example: voting lockstep for the long anachronistic voting rights act. Doing nothing to end anti-white discrimination. Doing nothing about the illegal alien invasion, one of the principal purposes of which is to transform whites into a minority. Who can think of any other example of either party supporting a large group which votes steadfastly against the party?
