Why I am against allowing ballots received after election day? (which is only allowed in ~15 states, others all disallow late ballots)
1) Unnecessarily strings out and complicates the entire election process, particularly for federal elections
2) Which, while it has no actual impact on election security, greatly reinforces the perception of the possibility of election fraud, which reinforces recent Republican disinformation campaigns.
Timely elections processes helps remove one path for destroying democracy through distrust.
And there is no reason to not follow the other 35 states in having a uniform deadline for ballot receipt (election day), as either mailing in ballot early or dropping in drop box on election day puts no impediment to voting.
