Sorry, but that's wrong. Since Reagan, they've hated each Republican president more than the last. Except for George H. W. Bush, who was too much of an empty suit to really get a good hate on. And it gets worse and worse.
Given that trend, they'll go nuts over the next one. By that time, Trump won't be so bad, like George W. Bush during the Trump years.
At a higher level, it's certainly alarming that so many people can be programmed to hate, so deeply, so quickly.
