The election may hinge on mail in votes.
The voter loses custody when the vote is delivered to the post office
The post office is controlled by the postal unions. The post office is not secure. The post office in in fact detrimental to a fair election.
A ballot not deposited in a ballot box s not a vote
A ballot in a ballot box is not secure either.
In my home town, the local “in” family had quite the time burning ballots to make sure their guy got elected.
Worked well till the “out” family hit them with a fire hose for burning inside the city limits. Got rather violent after that.
It does not matter who casts the votes, it matters who counts them.
I have always voted absentee. I will be voting in person on November 3. I don’t trust them.
