The issue is that you have offered absolutely no reason for why the Democrats would hate him, other than just saying that they hate him. And I've seen this type of argument before, that someone just hates an individual, but can't offer a reason for it. Is the issue that you cannot understand why Democrats hate Trump, or do you think they have no reason for it?
Among the 59 national emergencies, how many of them were declared after the President
If oncologists and cancer patients are unhappy with Trump's plans for cancer treatment, then why should I expect Democrats to applaud Trump? He also deserves no credit for peace negotiations when he had threatened to destroy North Korea. He banned Jim Acosta from the White House for asking a question, then used a doctored video from InfoWars to slander him.
Trump has tried to circumvent the separation of powers, and has gone out of his way to try and repeal Obamacare. Mitch McConnell was singled out for his hypocrisy in moaning about the opposition to Kavanaugh's nomination, because McConnell personally opposed Merrick Garland's nomination to the Supreme Court for absolutely no other reason than Obama nominated him. Republicans viciously hated Obama, as well as Trump.
Trump has also overseen attempts to ban transgender people from the military, and his Muslim ban was nothing short of discrimination. The hatred towards Trump is based entirely on him ruling more from his own irrational hatred than out of anything purely logical. Democrats detest him because he represents a regression in values. At the Munich Security Conference, Pence made a statement expecting an applause, and none of the world leaders present clapped. The United Nations laughed at Trump when he claimed that his administration has accomplish more than any other in history.
When the world is hating Trump, they're judging him for his reactions. I'm not saying that this isn't about Trump. You seem to believe that Democrats hate Trump as if his only crime was existing. My issue is that Trump has consistently operated in bad faith as president. The Russian probe against him is being led by Republicans because of the specific circumstances surrounding the 2016 election. All the hate against him is a reaction to what he has said and done.
If you truly believe that Trump has done nothing to earn the level of scorn he gets, take a step back and try to assess where he has gone wrong. Thankfully, Trump isn't the only president who's been hated this much. He's hated as much as Nixon was before Nixon resigned. Maybe screaming about a witch hunt in an investigation where several of the suspects have been found guilty could have something to do with that.
