To preserve election integrity, the postmark on the absenteee return envelope must be maintained and stamped no later than Election Day (not after). With no postage stamp or a postage stamp post dated after Election Day, fraud may occur. Without a postage stamp, people can add more and more ballots to skew results. Democracy and election integrity go together and are not disparate ideas. Abandoning election integrity is something that a Russian oligarch would do--basically that's why Putin wishes election after election. Don't make America like Russia.
