What did he do that was any good?  A failing health insurance program; unresolved conflicts with our greatest foes; huge drop-out of people in the workforce; wasted government dollars on belly-up green energy companies, promoting gender ideology nonsense, etc...  I don't want to debate the issue, except to say that these points are at best arguable, and just saying, "He did a great job" without further examination because he is Black would be more racist than making the substantive arguments against his policies.  So Trump is de facto racist because he criticizes Obama's policies and has a history of questioning Obama's birthplace (which, of course, remains debatable).  Sad.
