Oh. I kind of ignore Joe Biden in my political calculus. Obama's in a tough spot if his VP, former SoS, and a senator who campaigned for him are running against each other. I doubt Obama will choose sides, but I'd expect to hear more of "I'm friends with Joe," but not much more than that. Trump and Obama have a history, though, so if there's any speaking out from the White House, it will probably be to trash-talk Trump.
