The United States has a pretty aggressively racist head of state. Many state legislatures take steps to suppress voter turnout on racial lines. The North Carolina GOP did this just a few years ago in what was a pretty open and shut case.
So I see this repeated over and over again but I would like to know how you determine that Donald Trump is racist? Aggressively racist at that. Not that racist people support him. That's not the same thing as those same racist people may support more funding for space exploration but that doesn't make that policy racist. I mean how he personally, and in his role as President, is racist.

I do not mean this is a snarky manner, but words mean things.
