Bless his heart. He has no idea how mail ballots work (though he should since he votes by mail). There are a couple of key layers of security. 1/

First, on the claim that people could just “print thousands of forgeries,” you have to return mail ballots in an official envelope that is bar coded. This both provides a record that your vote was received and prevents duplicate voting. 2/

Second, in virtually all states, you have to sign the return envelope. Election officials can then match your signature to the one they have in their records. Here’s how the process works in Arizona. 3/

In fact, a many multitude bigger problem than “fraud” is that not all states give you a chance to cure a perceived signature mismatch like Minnesota does (see below ). Which is something all states should do or Congress should mandate. 4/
