Just follow directions like the rest of us who had to do mail ins before. It's not rocket science. If my adhd brained self could do it during college, I'm sure most of the people in this thread can as well. The issue is people don't read the instructions.

The reason it needs to be dated is because of voter fraud. Elections are heavily audited. If those envelopes aren't dated, they're not going to be counted. It's basic law. Your local poll workers and election officials aren't trying to suppress your vote.
