War game this:
Biden dies or drops out one week or days before the election.
DNC meets virtually and nominates Hillary. Administration and the courts refuse to delay the elections.
New generic, national ballots are printed and miraculously ready and distributed to states by the military.
All early and mail in ballots are voided.
Everyone has to show up on election day to vote.
All China’s fake pre-printed replacement ballots become useless.
