DENVER (AP) — Colorado’s secretary of state has appointed a supervisor to monitor Tuesday’s primary elections in a third county after some residents received ballots with the wrong state House districts and others received ballots that didn’t include a county commissioner’s race.

The state Republican Party had called for supervision of the Democratic clerk and recorder’s office in Pueblo County after Secretary of State Jena Griswold, a Democrat, appointed supervisors to oversee elections in two other counties where GOP clerks were accused of tampering with voting equipment.

Griswold appointed Drake Rambke, whom she described as a professional elections administrator, to supervise clerk Gilbert Ortiz’s office after receiving formal complaints of ballot errors committed by his office.
