If states or the Federal Government want to require proof of citizenship to exercise Constitutional Liberty THEY need to provide it FREE of Charge and readily available to ALL US citizens including Native Americans and Hispanics and all other US minorities. The Post Offics needs to provide residential addresses for all Native Indigenous reservation people as well so that their right to vote IS heard. This is just more GOP tricks to try to deny the rights to vote from millions who DON'T vote Republican. It is racist and violates our Constitution as well as that Congress was directed in 2013 by the SCOTUS to update Voter Rights Act protections when they struck down KEY parts of the 1965 voter right act. The HIP Congress has NOT fulfilled their Constitutional directive by the High Court to do so and in that time the third election in a row is seeing massive voter suppression efforts by the same party to who sought to strike down the protections to begin with.
