Of course, black people will continue to vote Democrat, as they will continie to correctly see the GOP as pandering to racists and trying to suppress the black vote. Contrary to the estimations of the detached, casual racists in this thread, black people aren't going to just be satisfied with lower unemployment, as the quality of those jobs still lags. And they will still see one party as trying to suppress efforts to help black people, while the other party engages in efforts to help poorer people.
I'm an 18 year old black man about to go to college. Would I vote for the party that demonize my community leaders, blows the racist dog whistle, engages in efforts to suppress my vote, and fights any effort to secure my education and future? Of course not. So dream on, people.
