The counterargument that poll watchers themselves may be partisan seems vague. How does this not apply to anything? Maybe they manipulated the ballots, maybe they reported the wrong numbers etc.. There's always a bureaucratic apparatus involved in processing an election and mail voting doesn't strike me as particularly exceptional. Why does the author trust that the French civil service is non-partisan enough? Here in Germany mail voting works exactly like described, outer ballot verifies identity, inner ballot contains the vote. There are always, I believe nine people required to be present when the envelops are separated to check on each other. To believe there is a systemic, effort across countless of voting regions with different demographics seems kind of conspiratorial.
