There are some problems with the ACT as is. The way it is currently written needs tweaking. For the most part, it does greatly burden anyone who has changed their last names since birth, mostly affecting women who have married. I read up on it and in 44 states, even Real ID's aren't sufficient proof of citizenship as per the SAVE ACT.
Even though I have a Real ID I would still have to bring my birth certificate and re-register. Last year I couldn't find my birth certificate and had to send off for a new one to get my Real ID, which took close to six months to get but, as I said, the Real ID by itself does no satisfy the SAVE ACT for proof of citizenship, even though I had to provide proof of citizenship to get my Real ID.
