Data from at least two elections – Wisconsin in 2020 and Virginia in 2021 – show that mail-in ballots have a distinctive partisan tilt. In both these elections, mail-in ballots trended Democrat. And in Virginia we can distinguish between mail-in ballots and in-person early voting. The latter trended Republican across the State and in most counties, even while mail-in ballots trended Democrat. One can accept this as an occasional result but not as a consistent one. It could mean that those inclined to ask for ballots by mail tend to vote Democratic. Or it could mean that the Democratic Party deliberately manipulates mail-in ballots to try to win elections. Only one way exists to find out: eliminate mail-in ballots and replace them with some form of in-person election service. And if the results swing back to the norm, then we have established, and eliminated a cause of, fraud.
