A viewer asks: “Is there a sting operation underway using secret watermarked ballot envelopes to expose rigging of the presidential election with fraudulent ballots?”

This is a rumor that has risen because that very thing has been discussed but was not implemented in time for this election, so it is a nice idea and would be a prudent safeguard should there be political support for assuring accuracy of vote counting. At the present time, that is not a high priority on the part of the Democrats.
