I think you find black presidents a lot in science fiction writing. It is a good shorthand for, “the world has moved beyond petty race differences” without having to come out and say it.

1924’s silent comedy, The Last Man on Earth. A plague killed all men over the age of 12. The Presidentress is one of several women fighting over the last surviving man (a hillbilly from the Ozarks).

Black women and Hispanic and Asian men, of course.
I envision a story about the first gay president and his First Man.
