TOPEKA, Kan. (AP) — A case playing out in a Kansas courtroom will determine whether potentially thousands of votes will be counted in November when they are cast in state and local elections by people who registered at motor vehicles offices or with a federal form without providing citizenship documents.

Shawnee County District Judge Larry Hendricks was scheduled to hear arguments Wednesday on whether to temporarily block Kansas Secretary of State Kris Kobach from throwing out the votes in local and state elections cast by people who fall into those categories.

The judge had earlier ordered the state to count them for the state’s August primary, and he must now rule on whether to extend that order for the November general election as well.

Meahwhile, a voting rights groups says registrations for thousands of Kansas voters have been purged

The League of Women Voters says that as of August Secretary of State Kobach has discarded the registrations of about 6,570 prospective voters under a rule that allows him to toss them after 90 days because they did not prove citizenship.

Those prospective voters likely registered at some place other than a motor vehicle office without providing citizenship documents, so their voting rights are not protected by recent court orders. They would need to register again to vote in November. Kansas requires proof of U.S. citizenship to register to vote.

The Secretary of State’s office says it could not immediately confirm the number.

The League purchased copies of the Kansas voter suspense list in March and in August, and compared them to calculate the number of missing registrations.
