What changes
BeforeThe primary election was held on the first Tuesday in August.
NowThe primary election is held on the second-to-last Tuesday in July. The 2026 primary moves from August 4 to July 21, 2026. The matching local election date for cities, towns, counties, school districts and other political subdivisions also moves to July, beginning in 2026.
BeforeProvisional ballots were checked against signature rosters and early voting records within 10 calendar days after a general election with a federal office, and within 5 business days after other elections.
NowThat check must happen within 7 calendar days after a general election with a federal office, and within 5 calendar days after other elections.
BeforeCounty party chairmen could appoint party agents or representatives to act as challengers for polling places in a precinct.
NowCounty party chairmen may also appoint them for any voting center, including in-person early voting locations and emergency voting locations. Limits on how many party representatives may be present at once now apply to each 'voting place.'
-
NowFor each ballot replacement location on election day, the county chairman of each party may appoint, in writing, a party representative and alternates to serve as observers. They must live in Arizona and be registered to vote here.
-
NowCandidate nomination petitions and city, town or county initiative petitions printed with the old August 4, 2026 primary date stay valid and may not be rejected only because of that date. Local election items already called for August 4, 2026 go on the July 21, 2026 ballot. Candidates do not need to file a new statement of interest only because the date changed.

What the law doesn't answer
- What Laws 2024, chapter 1, section 22 provides about signature curing and provisional ballot ID periods for 2026 federal elections; the act only says that law continues to apply and the curing time is not changed
- Whether other election deadlines, such as candidate filing or early ballot mailing dates, shift because of the earlier primary
- What observers at ballot replacement locations are allowed or not allowed to do
- How many observers per party may be present at a ballot replacement location at one time
- The reason the primary date was moved
