Dan Tokaji has written this post, which begins: “The Arizona Secretary of State is bristling at the Election Assistance Commission’s opinion letter from last Monday, which I previously discussed here. That letter concluded that the state may not impose stricter proof requirements at the registration stage than those provided for by the federally approved form under the National Voter Registration Act (‘NVRA’). To the extent that Arizona’s Proposition 200, passed by voters in 2004, purports to require additional proof of eligibility, the EAC concluded that those state-imposed requirements must give way to federal law.”
