evidence: Millions of these ballots are in states that mail ballots to every active voter — including states that have done so for years and those that did so in 2020 because of the pandemic. Adams’ group compiled a list of the 10 counties that it said had the highest number of "unknown" ballots, and nine of them were in states that mailed ballots to everyone, including California, Nevada and New Jersey. The other county was Maricopa County, Ariz., where about 75% of voters were on the permanent early-voting list, which means they get a mailed ballot for every election. [...] The U.S. Election Assistance Commission said that of about 90.7 million mail ballots sent out for the November 2020 election, about 15 million were ultimately placed in an "unknown" category. Millions of these ballots were in states that issued ballots automatically to all registered voters because of the pandemic.
