A few weeks after moving to suburban Kansas City from the Seattle area, Aaron Belenky went online to register to vote. But he ended up joining thousands of other Kansas residents whose voting rights are in legal limbo because of the state’s new proof-of-citizenship rule.

Starting this year, new voters aren’t legally registered in Kansas until they’ve presented a birth certificate, passport or other document demonstrating U.S. citizenship. Kansas is among a handful of GOP-dominated states enacting rules to keep noncitizens from voting, but the most visible result is a growing pool of nearly 15,000 residents who’ve filled out registration forms but can’t cast ballots.
