In my experience, people who literally hate Democrats, and hate illegal border crossers, are the ones who most love Trump. The hate, the love, are all emotional experiences. People who are a little more rational, and see things in shades of grey, and understand we have problems that can’t all be solved with a sledgehammer, aren’t as enthusiastic about him.
The “mean tweets” is usually where you can usually separate the groups. Those that love Trump actually probably love his mean tweets more than anything, even if they don’t realize it. But they revel in the good ones, and will defend every last bad one no matter how outlandish they may be.
Others realize that a sharp pretentious tongue often causes more harm than it does good, and have historically equated nastiness with liberal thinking and behavior. But of course we all see things differently, these are just my personal observations.
