Ballot access isn’t a problem, but the Biden/Harris campaign funds and the fact that nobody other than Harris can keep them is a huge problem.
Whole idea’s dumb. Whatever the formal process is, nobody who matters is going to challenge Harris for the nomination.
Yup. No state requires the major parties to certify their presidential nominees any sooner than August 21, and the state parties never do that until after the convention. As it stands now, it's no different than how they'd certify Biden when the time comes.
