Yeah, I think most people who want proof of citizenship are forgetting that your driver's license (even your REAL ID) isn't a proof of citizenship. It's passport, certificate of naturalization, or birth certificate.

Restricting voting to people with passports and who happen to have a birth certificate handy is going to make the first election with the requirement weird as hell and probably backfire on Republicans if their goal is winning at any cost.

Requiring some form of ID that your state is willing to accept as good enough is a very different beast than proof of citizenship.
