This is it to be honest.
Anybody who's Black and hip to how things work in this country would know that when you're Black in a top leadership position, especially the position of presidency, this whole idea of “going all the way” for specifically Black people isn't going to bode well with much of this country.
If he tried to do that, he probably would've faced impeachment, and unlike Trump, who's received a bunch of meaningless impeachments, that didn't prevent him from sitting in the White House, let alone running for a second term, Obama would've faced much more discipline, if not impeached out of the White House altogether.
I believe that in a perfect world, where Black people had the edge, he would've done more and by that I mean he would've done things (that these dudes be stressing out about) that might be considered unethical or biased but that ain't the world we live in, anything or anybody going all out for Black people, especially politically speaking, will lose and fall hard, society ain't gonna allow that person to prosper.
