Please, there is not one on that list of "Leaders" of the Black community that doesn't support Everything I listed.
I don't care what their leaders say because we are never going to convince Jesse Jackson or Al Sharpton to vote Republican. I care about what normal average black people say and having spoken to quite a few of them, many of them are reasonably conservative yet vote Democrat because they argue that the Republican Party is a home for racists and they don't want to be in the same party as racists. If this was an isolated comment that I heard from one person, I might dismiss it but I've heard the very same sort of comment again and again. Those "Leaders" you list maintain control the same way that dictators control people in the third world -- through tribalism and fear. They convince blacks that the Republican Party is out to get them. Since these "Leaders" are not going to magically convince blacks that these are lies, it is up to the Republican Party to convice blacks that they are not racist. And, yes, that means avoiding even the appearance of impropiety and making an extra special effort not to offend.
