A few reasons I can come up with:
1. He is the President. Even though I'm not a fan, if I had the opportunity to see the President of the United States in person, I'd do it. I've definitely more Democrat but I've gone to see GA Governor Brian Kemp AND Laura Bush when they came to my area.
2. He's a celebrity. He's bigger than life. I have comic books from the 90s that talk about the guy. My wife and I watched the documentary "American Pimp" from like 2001 and one if the Pimps had their picture with the guy!
3. Some people just like him. Hate him or love him, he has his fans that just adore him and will defend him to the death. There are people who have lost money due to his decisions and they still support him.
4. The Democratic party just sucks right now. To be Democratic, you have to "cosign" on a lot of things that you may not agree with because they want to appeal to everyone's morals. With Republicans, it's simple. Guns, no abortion, church. That's about it. There may be more. That's the gist of it. Also there's a strong "Looking out for ourselves" thing going on. People like when it's "Us vs Them".
