But to point out there might be “shenanigans”, you are automatically called an election denier, conspiracy theorist, against “democracy”, etc.
Yet, while creating laws that any ballot postmarks the day of the election, and allowing time for it for arrive at the counting location, is stupid. If you can mail it the day off the election, you could easily make it to the polling station to vote.
IMO, if it takes three days for mail within a state to be delivered, then the cutoff for mailing ballots is THREE-DAYS before election day.
Anything AFTER that is invalid. Does not count, etc.
