The democrats openly hate Trump for what I see is two reasons, he isn't a democrat and he is and has been on his own, not agreeing with the status quo. For democrats to hate this man and try to destroy him at all cost has been a complete failure, they wanted him out of their world of corruption at the very beginning. They miraculously could not bring him down, their goal right now is to stop him from winning again in 2020, chances are very good he will win so The democrats will go right back to trying to destroy him early in his second term.
He is not in the democratic party, and he is not on board with political corruption that is systemic corruption, he is the enemy !
When Trump was elected as a republican, he wasn't liked by the Party, but at first they were ****** to support him, they also are embedded into systemic corruption, not all, but without a doubt most, anyone that enters politics poor or middle class and becomes wealthy while in office, is corrupt. Trump is Corrupt as well but as Angelyn rightly stated he is not part of systemic corruption, Donald Trump has used corruption in the business world and is there for he is considered personally corrupt. I believe any billionaire in today's world is personally correct in one for or another. It is not right or moral but systemic corruption in the Government effects the people. ( the Clinton's, Obama and the Bush's all qualify ).
