 I think there were multiple things going on. I think that they feel Joe Biden is a president they can work with, have managed to get a lot of stuff done with on domestic policy. Who knows what Biden was maybe promising them in the background over the last few weeks as he tried to cling on. Bernie Sanders is personally close to Biden. He's probably had more access to this White House than any White House in history while he's been a senator or a member of Congress.
