Hard to believe, but you don't have to prove you're a citizen in order to vote ...

From The Associated Press:

 A federal appeals court has blocked Kansas, Georgia and Alabama from requiring residents to prove they are U.S. citizens when registering to vote using a national form.

The 2-1 ruling Friday said a U.S. election official illegally changed proof-of-citizenship requirements on the federal registration form at the behest of the three states.

People registering to vote in other states are only required to swear that that they are citizens, not show documentary proof.

The three-judge panel of the U.S. Court of Appeals for the District of Columbia acted swiftly in the case, issuing a two-page, unsigned ruling just a day after hearing oral arguments. A federal judge in July had refused to block the requirement while the case is considered on the merits.

The League of Women Voters and civil rights groups argued that the requirements could lead to the “mass disenfranchisement” of thousands of potential voters — many of them poor, African-American and living in rural areas.

The case now returns to the district court for a full hearing on the merits. But the appeals court said the voting rights groups are likely to succeed on the merits.

The change requires people seeking to register to show birth certificates, naturalization papers or other documents as proof of citizenship. Kansas has been actively enforcing the requirement, but Alabama and Georgia have not.

The appeals court’s ruling requires the commission to immediately remove the proof-of-citizenship requirement from all forms. It requires the states to treat all registration applications filed since January 29 as if they did not have the requirement.

Kansas Secretary of State Kris Kobach had argued that the change was needed to prevent voter fraud. He rejected claims that the requirement undermined voter registration, saying Kansas voter rolls have risen overall this year.
