Why do the southern blacks vote for Clinton?

Against their own best interests? Especially when those programs that economically and socially enslaved them did so with the full approval of the Clinton programs which Hillary vociferously endorsed? Just as the ignorant whites are for Trump, let's face it: those blacks voting for Clinton are uneducated and ignorant as well. Which of course is by design, only in this case the Democratic establishment of which Clinton is a part keeps them that way for exactly this reason. Aided and abetted, by the way, by black leadership.
