Chasing Olson for the second place on the November ballot, James Rogers had accumulated 13,271 votes, or 34.41 percent, in the early count. That places Rogers 3,634 votes behind Olson in these returns. Ciara Anderson trailed the two leaders with 8,395 votes, amounting to 21.77 percent, leaving a gap of 4,876 votes between her and Rogers based on the figures published in the early report.
The report noted that one of the two seats tied to Legislative District 10 is being contested without an incumbent candidate, while Olson remains the district’s lone sitting representative in this race. Those conditions framed much of the attention on the district’s primary results as the initial tallies became publicly available.
The three candidates’ vote totals and shares in the early returns illustrate the margin that has formed among them at this stage of counting. Olson’s 43.82 percent share of the reported ballots positions him as the front-runner in this phase of the primary tally. Rogers’ 34.41 percent gives him a clear lead over Anderson for the second reported position on the November ballot, based on these early figures.
Numbers reported in the initial release allow for a straightforward comparison: Olson’s lead over Rogers measured 3,634 votes in the returns published through early Wednesday, while Rogers led Anderson by 4,876 votes in the same snapshot. Those differentials reflect the state of returns in the early reporting window and do not include any later updates or additional precinct reports that may be posted after that cutoff.
The early results were presented as part of the primary election returns made available in the morning report.

The published figures—the vote totals and percentage shares for Olson, Rogers and Anderson—were the primary elements provided in the early morning release of returns for the LD10 House contest. The report emphasized Olson’s position as the lone incumbent within the district’s House delegation and highlighted that one seat in the district was being contested without an incumbent in the primary cycle. The numbers cited above reflect the returns released through the early Wednesday morning reporting period.
Olson thanked LD10 voters on X for their support after the primary, calling it an honor to represent East Mesa for four terms and expressing humility at the continued backing. Final results confirmed he and James Rogers prevailed to secure the Republican nominations, setting up a November contest against Democratic nominees Helen Hunter and Brian Calaway.

Arizona moved its 2026 primary to the second‑to‑last Tuesday in July (July 21) under a state law change enacted this year, a scheduling shift election officials said was intended to give more time for preparation and for military and overseas ballots before the November general.
Local reporting in mid‑July flagged a controversy around Republican candidate Ciara Anderson’s military service: public records and contemporaneous reporting indicated a court‑martial and a Bad Conduct Discharge, and several high‑profile endorsers told reporters they had not been aware of those details before the campaign disclosures.
