If she made her own foreign policy decisions in either of those jobs then fine. But I expect the President had the last word. In any case, I'd be fine with her or Susan Rice but not sure Biden would consider either to be ready on Day One to be President.
Based on this argument Biden wouldn't pick himself as VP, b-man.
And your granddaughter is more qualified to be president than the sad, scared little man occupying our White House. #BunkerBoy
