Re-vote is not a good idea. The dems now know how many votes they need to make sure that Nelson wins. However, if they should decide to do that, then first they need to purge the voter rolls of dead people, and only allow those who voted in the election originally to vote, after ascertaining they are who they say they are and that they have ID. There is still a problem, though, with an accurate absentee ballot vote.
Well, the idea is a carefully monitored re-vote. ALL ballots validated. Not a redo of what already happened.
