Well, no question; more to the point, she plans to be President.
Bit going in as a VP has some real advantages; she can just 'step up' to the power podium when a 'fate' takes over the President.
I cannot imagine any Dem candidate seriously wanting her as a VP, hovering just a step away from the Oval Office. And she will rule with or without that acting president.
But probably there will be little 'choice' in the matter.
The Secret Service would be criminally irresponsible to allow Hillary as VP.
