Add to the list:
All absentee ballots must be received by 7pm on election day; no exceptions.
Each precinct keeps the vote totals locally.
Have the vote totals nationwide held till 9am the day after election day.
Then add everything up and release the results all at once.
Added. I'll be making more additions to the page. Note the postmark caveat I added.
All absentee ballots must be received (not just postmarked) by 7pm on election day; no exceptions. H/T WildHighlander57
