i would say Barack Obama. he did so much for the U.S and not only the U.S but the world too his speeches are inspiring he created a lot of child cares and affordable ones too he gives charity he visits children in school, hospital, library..etc and he stopped the great depression from happening again which was in 2009 or 10 (don't remember) he gave Ellen DeGeneres the right to marry a women legally.
so yeah thats what i got so far XD
