Well, in his defense, it's not policies per se. However, by any normal standard, he's been inflammatory and incite-ful. It's fine for a community organizers. Not so much for a President. That said, he sure paved the way for Trump.
In any event, I'd LOVE to sit with Obama and ask him what his intent is. Is it to have a certain amount of blood letting for some sense of get even-ness for the past? Is it simply pay back to Al Sharpton, he has to help Al's buisness because Al helped him get elected? (do not forget that Sharpton and others said Obama, in 2007 and early 2008, was not black enough, was not from the civil rights struggles and was, ironically enough, appropriating black struggles). Is it simple raw power politics, squeaky wheel gets the grease?
He's not a moron. He has to know that when you take that power, of the bully pulpit, and you're backing a couple of losers, sooner or later, it blows back. So, why?
