Barring some major gaffe or episode from Biden, this election is over. I understand people are still fearful of 2016, but Hillary was not leading by an average of 9-10% nationally in October 2016.
The biggest risk now is Trump and the GOP attempting to have all mail in ballots thrown out.
Even more importantly, she was never over 50%, something we are routinely seeing for Biden now - the highest she ever got in the averages was about 46%, due to the larger number of voters saying they were undecided or planning to vote third party.
