honestly, could be a hot Arab man as long as he's not a terrorist, or an Italian but as long as the d isn't bigger than his; but no Russians or Jews, and we already know he won't approve of a black man.
he's strictly forbidden anyone more fuckable than he was in his early 30's, so no one stunningly gorgeous or super intelligent, unfortunately. cannot be royalty cause then we'd have geopolitical issues. he prefers immigrants cause they're easily manipulated, no American-borns cause they're not. no Democrats or liberals, centrists ok as long as they stan Donald Trump and promise to pass me back to him on demand like a football even tho he isn't good at sports.
in general, just don't be cooler or hotter than him and it'll be fine.
