I don't remember having to sign my name. I do remember having to recite my address. When I first registered to vote there several years ago, I had to sign my name, provide the photo ID and proof of residency, etc, BUT I think they had us sign on one of those electronic tablets that don't even look like your real signature. I also remember that at the time I first registered to vote here in MO, the driver's licenses were NOT the "real ID" ones. We did get a real ID license when we renewed it a few years ago, BUT they gave us an option NOT to spend the extra money on that and just give us the other one instead. THAT is what makes me wonder.....
