Barack Obama begs to differ.

SANDERS: “Well, I think both to be honest with you. Look, in my view, Donald Trump is the most dangerous president in the modern history of this country. He’s a pathological liar. He’s a racist, a sexist, a homophone, a xenophobe. This is somebody who should not be president. I’ll do everything I can, if I’m the Democratic nominee to defeat him and I will support if I lose somebody else, whether it’s Joe, whether it’s somebody else. We’re going to defeat Donald Trump.”
