Pure idiocy. You're talking about politically involved people who supported a candidate who campaigned for their vote. You're talking about a candidate who did not have support from a community he virtually ignored.
Ignored? He talked directly about issues that affect black Camoonities, NEARLY EVERY SINGLE FUCKING SPEECH. Hillary did not do this at all, nor did she make even a quarter of the campaign stops in the South or give even a fraction of a quarter of speeches. Hillary did not even hold any press conferences (still hasn't) whereas Bernie had several a week. Bernie was also on TV programs, news stations as much as possible. Hillary was not and STILL is not. Her campaign strategy was "The less you see and know of her, the better". Hell, she did not even bother going to some states whereas Bernie went to all states.
If anyone did enough, it was Bernie. You can pull their schedules and see the proof.
Again, the only conclusions you can draw is that blacks are really that stupid that they need special treatment and special explaining to. The news networks, the entire internet and the rest are not enough for blacks. You even admit yourself that that blacks need this special treatment. Its what is known as the soft bigotry of low expectations. You have just told us they are too dumb to seek out info via conventional means and that they need special preaching to whereas whites, and everyone else do not require this.
Its pathetic really and we can only conclude that they really are that stupid. Perhaps even dumber than we, (even you, may realize). You seem to not expect much from them either as you admit they need special treatment in order to understand basic concepts.
