Jesse Jackson hates it when people stoke racial resentment. He doesn't need the competition.
As someone who's not plugged into cable news, or the Twitter-verse, it seems to me that the people making Trump's campaign/presidency into The Bigotry Campaign are Leftists like Jackson. (Well, mainly, it's Lefties that aren't 80-million years old, and long past relevance, but you know what I mean.) But like I said, I haven't really been keeping up with all of Trump's speeches and tweets. Maybe I'm wrong.
Not that I'm saying Trump hasn't made some insensitive, or even racist comments, but it seems as though the left wants that to be the whole focus of his campaign. The Democratic Party always seems to fall back on race-baiting. It does usually work for them.
