And people think Trump has the big ego? This guy actually thinks he can tell Republicans what to think and do. On second thought, he’s been doing it for 8 years now, so, never mind.
As you noted, Obama can and has told the GOPe what to do for almost eight years. It’s therefore not completely unreasonable for him to expect that he can continue to do so.
Problem for him is that we are rejecting the GOPe.
