Election officials across Kansas are expected to begin removing the names of more than 31,000 prospective voters from their records in line with Kansas' tough voter identification law, which requires applicants to prove their citizenship before casting a ballot.
Secretary of State Kris Kobach has directed county election officials to discard applications from prospective voters who after 90 days did not provide all the required information and documents.
Most were people who hadn't documented their U.S. citizenship.
The proof-of-citizenship requirement took effect in 2013.
Only four states have a similar requirement, which advocates support as an effective tool against voter fraud but opponents consider a ruse for discouraging voting by the poor and minorities.
The culling of applications is the first since the law went into effect.
