Wichita (ap) — The Kansas primary elections tested a dual voting system that counts votes for federal offices cast by people who registered using a federal form without proving their citizenship.

It’s unclear how many of those registrants actually voted Tuesday. But the Sedgwick County election office said Wednesday a “quick check” of 1,100 provisional ballots did not reveal any names that matched its list of federal registration applicants.

Secretary of State Kris Kobach has instructed counties to give provisional ballots to voters who registered on the national form without documentation of citizenship.
