In theory she could try to boost black support by picking a black person for VP, but it is hard to see how any of the obvious choices would help the ticket (Spartacus, Kamala, Al Sharpton, Stacey Abrams, Al Green, Elijah Cummings, Maxine...). A ticket with no white males on it would be a first.
She might be the worst of the lot when it comes to ignoring those state borders.
Everything with her is a national this or national that. And even more annoying is her pronunciation of it as NAIYSHUNUL.
