No advice to give you - just sharing my somewhat similar story. I built my house new in 2004 and my wife and I are the only legally registered voters that have ever lived here. About a week after the stolen 2020 election, I received voter registration info (precinct, stated party affiliation, etc) for a woman that I do not know, that listed my home address as their home of record. I reported this info to my local election supervisor (county clerks office) and was told that someone from their office would "look into it" and give me a call back - I never received a call after 2 weeks. I called them back and was told the same exact thing and once again never received a call back from them - my entire county elected officials are democrats so no shocker there. I reported all this to my state GOP office - they said they would record my complaint but that there was nothing they could do about it. Now, as we approach the midterms, I received more voter information stuff from our county clerk's office - one for my wife, one for myself...and one for the person using my address to illegally vote. I once again contacted the county clerks office - they transferred me to the election supervisor - she told me that their office received the voter registration from the DMV and what "probably happened" was that one of my neighbors (who I know all of them by name and none of them match the name on the form, not even close) "probably" put down the wrong address and it would "probably" be rectified if the "voter" shows up to vote because they list voter information on the rolls by name and verify by address (but they do not check ID). I reported all this to True The Vote - I don't really expect them to be able to do anything about it but at least I could vent my concerns with someone that at least gives a shit.
