Of course they "played their part", but Obama's part was a Constitutional Law Professor turned Senator and then President. Trumps part is a WWE character, con man, and game show host. The two men eat, breath, and sleep. Aside from those pretty much everything else is different. Just look at the quality of Trump's picks for agency heads. Obama never picked anyone to sabotage an agency because he has ethics. Trump doesn't know the meaning of the word.
