CHRIS STIREWALT (POLITICS EDITOR): [Elizabeth Warren] is interested in extracting the maximum benefit, the maximum concession for her endorsement. Look, she and Bernie Sanders are not friends -- they have never been friends. You will recall in one debate, by the way, he accused her of lying and she accused him of sexism. So it's not like that's been -- that's been a non-aggression pact, not a friendship. Is she aligned with Bernie Sanders ideologically, probably more so than Joe Biden, but is not a perfect fit. So, what she's either got to do is get a little from Bernie Sanders or a lot from Joe Biden, and that's what she's probably trying to figure out.
HARRIS FAULKNER (HOST):What does that look like, a lot from Joe Biden?
STIREWALT: Running mate, cabinet secretary, promise to do XYZ, promise to hire her staff, to rub his belly and pat his head, whatever she wants. Her endorsement of Joe Biden would be so valuable to him. It would be -- Bernie is almost done, but it would cut the legs right out from under him. So he might be willing to pay a lot. But she is real difficult to deal with and she doesn't get along with people.
