On Obamacare, every day that goes by I have more evidence that I wish I could put in my book, on how difficult it is for the Republicans to eliminate this law. They have no real alternative. They're afraid to take away health care from the 20 million people who now have it.

Barack Obama is pretty similar to the person you see in public, at press conferences. He's a little saltier, a little more sarcastic and cutting.

In some ways, Trump is just going to continue the trend: by continuing the norm-smashing behaviour that Republicans used in opposition.

In public, Barack Obama's giving the simple version of his beliefs for the mass public. In private, he can discuss it at a really high level.

Barack Obama is a very impressive human being.

Trump is what Obama critics think Obama is: Someone who's focused on symbolism rather than substance.

Liberals tend to romanticize the past, past leaders' failures.
