It is hard to believe that Obama is sober enough, or has enough ambition to care about any of this. Obama only ever cared about Obama. I don't think he give a single shit about 'legacy' or about anything else.
The people pushing this Obama is God meme, are people trying to cover their ass. They know he was a disaster, but the special interests can't allow that to stick. How can they ever get another Black or any minority elected with the scorched Earth Obama left all over the world in his wake? They have to portray all of Trump's successes, as Obama successes. And all of Obama's failures were the fault of evil Jews who were sabotaging him.
This is not Obama speaking. Obama is passed out stoned out of his head somewhere on a beach with Reggie Love. These are DNC "fixers" pushing all of this. They are not doing it for Obama. They are doing it to save face for the DNC for ever electing the incredibly underqualified slacker party animal who had no resume', in the first place. And to try to pave the way for another try with another underqualified Black or Latino racist in the future.
