TOPEKA, Kan. (AP) — As many as 50,000 Kansas voters who registered at motor vehicle offices would be given provisional ballots in the upcoming elections only to see their votes thrown out in state and local races under a proposed temporary rule. The State Rules and Regulations Board is meeting Tuesday to consider the temporary rule sought by the Secretary of State Kris Kobach. The rule calls for counting only the votes cast for federal offices unless the voters provide documents proving their U.S. citizenship. Notice of that meeting went out late Monday for a temporary rule that would be in effect for upcoming elections. The temporary rule is necessary because of ongoing court challenges to the state law requiring documentary proof of citizenship to vote.
