In Virginia's case, her second vote would be valid since her first vote occurred before the vote even happen. I'd be interested in hearing Truman's reasoning on this since he keeps advising people that they can delete their votes and re-vote, I personally don't see how it is much different from editing your vote after 20 minutes (illegal).
If there isn't a court case (not too much point since it won't change the results), I strongly urge Congress to pass legislation clarifying that it is prohibited for individuals to delete their votes and revote.
How do you enforce that though aside from eyewitness?
He admitted to it though privately.
