China, Russia, and Iran have all jumped into the pigpen early -- on different sides.
#45 has already sabotaged the election by attacking the post office at a time when more citizens will vote by mail. That means, regardless of the outcome, the election process itself is questionable.
Also, even if #45 loses the election, he might simply refuse to leave.

Confirm your registration or register to vote. If you haven't done it yet, do it NOW. Waiting gives meddlers more opportunity to tamper.
Take other steps to protect the election.
Try to make sure your vote is counted.
