Arizona’s voter registration forms don’t adequately tell people with a felony about their voting rights, potentially disenfranchising scores of people, an election-law, advocacy group claims.

A federal appeals court has refused to reconsider a decision allowing residents of Kansas and Arizona to register to vote using a federal form without providing proof of their U.S. citizenship.

Kansas and Arizona residents can continue to register to vote for now using a federal form without having to provide proof of citizenship, a federal appeals court ruled Thursday.

A federal judge’s order backing Arizona and Kansas laws that require proof of citizenship for voter registration is “not the American way” and must be challenged, opponents said Thursday.
