Kansas Voters Approve Amendment to Restrict Voting to Citizens

With nearly all precincts reporting at midnight, Kansas voters passed a constitutional amendment 64% to 36% that rewrites the state’s voting clause to state that only U.S. citizens can vote — language the Kansas Constitution already contains — a result supporters call a needed clarification and opponents fear will be weaponized to demand birth certificates and passports at the polls, Kansas Reflector reported.

The amendment shifts the constitutional text from “every person who is a citizen” can vote to “no person can vote unless they are a citizen,” according to the Kansas Secretary of State’s official page on proposed constitutional amendments. Backers say the new phrasing closes a loophole, but the change arrives with the state Constitution already guaranteeing the same right, leaving critics to ask what problem the 64% majority actually solved.

A Semantic Shift With Legal Teeth

The difference between the old and new language is small on its face but potentially large in a courtroom. Amii Castle, a law professor at the University of Kansas, said the amendment is difficult to explain precisely because the change sounds minor.

“This amendment is hard to explain to folks because first off, it doesn’t sound like that big of a change going from every person who is a citizen can vote to no person can vote unless they are a citizen,” Castle said.

Castle and other opponents argue that “only citizens” invites a different legal standard than “every person who is a citizen,” one that could justify requiring voters to prove their status with documents rather than simply affirming it under penalty of perjury.

“The supermajority in our Legislature has a documented history of attempting to restrict voting in various ways,” Castle said. “My concern is that they’re going to use that to justify or as a pretext to say, ‘Well, wait a minute. We amended our constitution. Now it says only citizens can vote, therefore, prove your citizenship. Bring your documents.'”

The Documentary Burden on Voters

The Brennan Center for Justice found that about 9% of American citizens of voting age do not have proof of citizenship documents “readily available.” The disparity is not evenly distributed: while just over 8% of self-identified white American citizens lack readily available documents, that number rises to nearly 11% among Americans of color.

The paperwork problem extends beyond birth certificates. Voters who have changed their names — through marriage, for example — would need to show additional documents linking their current name to their citizenship record. A birth certificate establishes citizenship, but a married voter who took a spouse’s name would also need a marriage certificate to connect the two, stacking requirements that some eligible citizens simply do not have on hand.

The Legislative Playbook Already Exists

Rep. Pat Proctor, who led the effort to place the amendment on the ballot, framed the measure as a way to ensure only citizens can vote. Proctor also noted that Kansas previously attempted to pass a proof-of-citizenship law, but the Kansas Supreme Court struck it down as conflicting with federal law.

Castle said that ruling is not necessarily permanent protection. A change at the federal level could reopen the door for Topeka to try again.

Vote YES on the Citizens-Only Voting Amendment

“There is the SAVE Act in Congress that was passed by the House and not by the Senate, but they ain’t done,” Castle said. “The SAVE Act explicitly would require documentary proof of citizenship to vote in a federal election.”

If Congress passes the SAVE Act or similar legislation, the new Kansas constitutional language could serve as state-level justification for enforcing document checks that federal law would then permit, transforming a symbolic wording change into a concrete barrier at the ballot box.

What the 64% Actually Changed

Kansas already barred noncitizens from voting under its existing Constitution, so Tuesday’s vote did not alter who is legally eligible to cast a ballot. What it altered is the textual foundation lawmakers can cite when writing future election laws. For the 36% who opposed the measure, the amendment is less about election integrity and more about building a constitutional ramp toward stricter registration rules — rules that research shows would fall hardest on citizens of color and anyone who has changed their name and lacks the paper trail to prove it.
