I got one a few months ago and ignored it. I got threatening notes everyday so I called my congressman’s office and told them it wasn’t a census year, I wasn’t filling out a government form providing very personal information. I wanted them to leave me alone. I never got another note or visit.
Just like anything, if enough people complain, they will perhaps do something about it.
Wrote to Ed Royce... Got the standard political weasel non response response. Guess he goes in the RINO column for me!
