Kansas secretary of state and national voter suppression advocate Kris Kobach has been struggling in recent months to implement a new “proof of citizenship” voter registration requirement that he pushed into law. But now he has a new plan: sue the federal government to make it harder to register to vote with a federal form in his state.

Like a similar Arizona law that was recently struck down by the Supreme Court, Kansas’ law requires those registering to vote to produce documented proof of citizenship beyond the sworn oath required on federal voter registration forms. This has produced an administrative nightmare in Kansas, throwing the voting status of at least 15,000 people who registered with the federal form into limbo.

Kobach’s first plan to fix this was to force the thousands of Kansans who had registered with the federal form to cast provisional ballots in the next election, which would then only count if they showed up later at an elections office armed with a birth certificate or other citizenship document. The state board of elections rejected the plan, which one Republican state senator called “disingenuous at best.”

Kobach then got creative, suggesting that Kansas create two classes of voters, with those who register with the federal form only allowed to vote in federal elections. Voting rights advocates balked.

Now, Kobach has a new plan. Along with Arizona Secretary of State Ken Bennett, Kobach is suing the U.S. Election Assistance Commission to require the federal government to add extra “proof of citizenship” requirements to federal voter registration forms in the two states. Andy Marso at the Topeka Capital-Journal sums up the scheme:

Facing the possibility of legal action over 15,000-plus suspended voter registrations, Secretary of State Kris Kobach struck back by announcing Wednesday his own suit against a federal election commission. Kobach said at a news conference that he and Arizona Secretary of State Ken Bennett, both Republicans, have filed a complaint against the U.S. Election Assistance Commission asking that federal voter registration forms issued to residents of their states include state-specific proof of citizenship requirements like the ones on state forms largely responsible for putting thousands of Kansas registrations on hold. Kobach said the court case is “the first of its kind.” Kansas voters will be best served when the EAC amends the Kansas-specific instructions on the Federal Form to include submitting concrete evidence of U.S. citizenship when registering to vote,” Kobach said. Kobach said the lawsuit would partially preempt a suit being prepared but he American Civil Liberties Union over the suspended registrations. “It does block many of the arguments the ACLU might wish to raise,” Kobach said.

Kobach explains that he is answering the “invitation” that Justice Antonin Scalia left in his opinion in the Arizona case, in which the justice suggested that Arizona try such a move.
