Arizona
Fifteen counties publish election results fifteen different ways, through four vendors and one raw PDF. One of them holds fifty-nine percent of the electorate, and the largest bloc in the state is a category the state calls Other.
Which party leads Arizona registration?
State deltas
Every state has hair. Here is Arizona's.
The rules that make this state different from the last one, what each breaks if you assume the national default, and how the engine resolves it.
The Secretary of State publishes a per-county results link for all fifteen, and they resolve to four commercial vendors and eleven other things: Clarity for Greenlee and Yuma, Enhanced Voting for Mohave, Live Voter Turnout for Pima, a bare PDF for Apache, and county-hosted pages for the rest. Gila's link points at the county homepage rather than any results page. A single county-results adapter covers one county here; a vendor-shaped adapter covers four counties between them.
Results vehicle is a per-county field with the endpoint recorded, not inferred from the state. Vendor-hosted counties share an adapter; county-hosted pages and documents each carry their own, and a link that resolves to a homepage is flagged rather than parsed.
Every Arizona county splits election administration between an elected County Recorder — voter registration and early voting — and a separate Elections Director for election day, voting locations and tabulation. Thirteen counties run that pair. Pinal's Recorder holds both roles under two sets of contact details. Maricopa runs three offices, splitting the election half again into Election Services and Early Voting versus Election Day and Emergency Voting. A schema with one election-official contact per county is wrong in all fifteen and badly wrong in Maricopa.
County officials are modeled as a list of roles, not a single contact, and the role vocabulary is read from the state's own labels — registration and early voting, versus election and voting location information.
Arizona reports registration in six columns — Republican, Democratic, Libertarian, No Labels, Green and Other. Other holds 1,490,185 registrations, 34.60%, second only to Republicans and ahead of Democrats. Unlike Colorado's eleven named columns, the state's published statistics cannot distinguish an independent from a minor-party registrant from a decline-to-state. Any model that reads a party breakdown as exhaustive silently attributes a third of Arizona to nothing.
Residual categories are carried as residual, never as a party and never redistributed. Where a state publishes a genuine open vocabulary the extra columns are kept; where it publishes a bucket, the bucket is labelled as one.
Maricopa holds 2,540,618 of 4,306,554 registrations and 956 of 1,764 precincts. Greenlee holds 4,564 across 6. A per-county completion metric reads 93% when Maricopa alone has failed, and any statewide figure built by averaging counties rather than weighting them is off by an order of magnitude.
County coverage is reported weighted by registration as well as by count, so a Maricopa failure cannot be averaged away by fourteen small successes.
Arizona elects a State Mine Inspector statewide on a four-year term, and elects rather than appoints its Corporation Commission — the utilities, securities and incorporations regulator. Both appear on the 2026 mid-term ballot: one Mine Inspector, two Corporation Commissioners. An office taxonomy built from the common statewide set drops both, and a Corporation Commission seat is not a public service commission seat by another name — the constitutional powers differ.
Office inventory is read per state from the state's own term table rather than mapped onto a national template, and offices without a national analogue keep their own identity.
Between the January 2026 and primary-election reports, Cochise went from 55 precincts to 57 and Navajo from 21 to 19. The statewide total is 1,764 as of July 2026 and was not that in January. Precinct identifiers keyed to a single snapshot break across the same cycle, and a year-over-year precinct join silently mismatches two counties.
Precinct counts are stored per reporting period with the period attached, never as a single current value, and joins across periods are asserted rather than assumed.
Read on August 14, 2026, the Secretary of State's results portal reports the July 21 primary at 100% of precincts, 1,181,331 ballots cast and 27.43% turnout, last updated August 5 — and labels the whole thing <b>Unofficial Results</b> under a banner reading <b>Preview</b> and <b>TESTING SITE</b>. Twenty-four days after the primary there is no certified canvass on this surface. Treating election-night numbers as final because they are complete and stable is exactly the error the labels are there to prevent.
Unofficial and certified are separate states with separate provenance, never merged on the strength of a 100% precinct count. The page carries the state's own label and its update timestamp.
Arizona's Senate seats are Class I and Class III. Neither class stands in 2026, so despite a full statewide ticket and nine House races the state elects no senator this cycle. A ladder generated from the assumption that every state has a Senate race in a mid-term invents a contest that does not exist.
Senate classes are modeled per state and per cycle from the state's own term table; the federal tier is generated from what is actually up, not from a template.
Federal to school district
What Arizona actually elects.
The Secretary of State is the filing officer for federal, statewide and legislative offices — 107 of them in 2026. Everything below that line is filed with the county, and the state's guidance says so plainly: for local information, contact your county recorder's office.

County ledger
One state portal, and fifteen counties that publish fifteen different ways.
Precincts and registration below are the state's own July 2026 primary-election report, read August 14, 2026 — the same file whose fifteen county rows sum exactly to the published statewide total of 4,306,554. The vehicle column is not inferred: the Secretary of State's results portal publishes a results link for every county, and the classification below follows those endpoints. Thirteen of the fifteen counties are shown; Graham and La Paz are the two omitted.
