Incumbent Tom Horne and state Treasurer Kimberly Yee remain locked in a tight Republican primary for Arizona Superintendent of Public Instruction, with the July 21 vote just weeks away and early ballots already distributed. Recent negative advertising funded by an outside group targeting Yee has drawn condemnation from both candidates and former superintendents, while Yee has secured endorsements from four prior Republican officeholders emphasizing her fiscal and education policy record. The pair has also clashed publicly over credit for technology improvements in the Empowerment Scholarship Accounts program. These late-cycle developments, combined with Horne’s incumbency and narrow 2022 win, sustain the even trader consensus reflected in current market pricing ahead of primary results.
