A way long time ago, when I was young, I was going to be out of town on election day. I applied for an absentee ballot.
The hoops I had to jump through were astronomical.
We need to go back to that.
And valid ID
Something on the order of what you mentioned might be at least a partial answer to the mail-in ballots. I don’t know what wording is used on those ballots, but maybe it should be revised to make it tougher to falsify them. Providing HEAVY penalties for any that should be proven false might be at least a partial answer. These ballots should include a name(s) of those providing the ballot for the voter also.
