Obama was a charismatic once in a generation political talent only rivaled by JFK and Bill Clinton. He was able to overcome the racial issues that would hinder any other minority Presidential candidate because of how talented he was.
On top of that, it took Bush leaving office with a 22% approval rating, 2 unpopular wars, and a economic collapse for white people to say "lets give this nikka a chance"
Obama does not apply to the current situation. As a matter of fact, fukk Obama. He gave us Trump and now that he's ran Biden out of the nomination, he's going to give us Trump again.
