After this past election cycle, I was getting spam SMS from every organizer in each county I have lived in over the past 10 years. Does anyone know any master list to remove contact info? Replying “stop” to each text message wouldn’t prevent others from getting through.
I don’t have an answer to you, but I changed my affiliation to No Party Preference after undergoing the same deluge of election spammers. When I asked them how they got my info it came from the Democratic Party (which I am thankfully now no longer registered for. Not sure why I ever made the mistake of signing up...)
You'll need to go to the RoV (Registrar of Voters), BoE (Board of Elections), or equivalent for those counties, and submit the paperwork to un-register. That should remove you from the voting rolls there.
