Everyone loved Trump, and was happy to be seen with him. And that includes Al Sharpton and Jesse Jackson. Then Trump beats Hillary, and all of a sudden he's a monster.
They considered this defection by Donald J. Trump as a total repudiation of all that they once believed and stood for. How dare he put action to his words, and REALLY run for President, as he had so often brought up in conversation before?
Trump was always just supposed to fund the candidacy of someone else, preferably high-level sophisticates who understood the nuances of the world, and praised their satisfaction with “helping” the less fortunate, by making them “happy” in their destitution.
In other words, keep the status quo, while maintaining their own high position.
