>Why would tourists want to come to a place they dislike?

Visit family.

That's not mentioning you can dislike the current administration without disliking other aspects of the US. The US is big and diverse.

It's not even about like or dislike. Some people dislike the UK, but I imagine that few feel threatened by the prospect of having to cross its border. It's an easier sell to make someone come to the country despite whatever they don't like to attend a big event. But with the US, who knows at this point? The system had been shaken up so much in the last year that there's no telling what's going to happen to any given entrant (especially someone from one of the "disfavored" countries), or what the rules are going to be like tomorrow. It's not preference, it's preference combined with fear.
