The mail carrier has a "side pile" for all ballots coming from a home with a Trump sign in the yard. That "side pile" gets thrown in the trash.
My state (Washington) has all-mail voting, no exceptions. Rather than mail them, I will be putting my ballots (1 for me, 1 for the wife, and 1 for my oldest son) in the ballot collection box right in front of the county elections office.
I appreciate the mail carriers and what they do, but as for the election, I trust the US Mail as far as can throw them
Mail carriers also see the return address and logo info on mail you receive. Maybe we all should sign up for RAT literature.
Recently I passed through a wealthy suburb and saw very few yard signs. Those I did see were for local races only, not presidential. Did see maybe four Biden signs but that was it. No Trump signs. Peculiar.
