Louisiana

The jungle primary ended here in January and came halfway back in May — a sitting senator lost renomination under the new rules, and the House races that were pulled from the ballot had their votes voided.

Two primary systems are running in the same cycle. Act 1 of 2024 moved Congress, the Supreme Court, the PSC and BESE into closed party primaries — the first congressional party primaries since 2008. Then the U.S. Supreme Court decided Louisiana v. Callais on April 29, the governor pulled the House races off the May ballot, and Act 7 reverted them to the old all-comers system for this cycle only: votes already cast in those races were voided and never released. So the Senate ran under the new rules and lost its incumbent, while the House runs under the old ones on November 3 with a December 12 runoff.

What happened in the Senate race?

The new closed primary claimed its first incumbent. On May 16, Bill Cassidy finished third with 24.8% — the first elected sitting senator to lose renomination since Lugar in 2012. Julia Letlow took 44.8%, then the June 27 runoff 56.9% over John Fleming. The Democratic nominee is Jamie Davis, a police juror from Tensas Parish — the smallest parish in the state at ten precincts. November 3 is a two-candidate ballot; no independents qualified.

Δ 01Two primary systems, and the map changed which offices use whichNew this cycle
Breaks

Act 1 of 2024 moved Congress, the Supreme Court, PSC and BESE into closed party primaries effective this year. Then SCOTUS decided Louisiana v. Callais on April 29 — Louisiana was the case — the governor pulled the U.S. House races from the May 16 ballot, and Act 7 reverted them to the jungle system for this cycle only. Votes already cast in those House races were voided and never released. A crawler holding either the old model or the clean new one is wrong, and a candidate list captured in spring does not describe November.

Resolved

Primary system is modeled per office per cycle, legislatively versioned — not as a property of the state. The voided May House results are excluded from the general-election pipeline rather than carried forward.

Δ 02Elections are held on Saturdays, with different poll hoursScheduling
Breaks

The party primary, its runoff, and the December general all fall on Saturdays; only the November federal general sits on the usual Tuesday. And the hours differ by day: Saturday elections run 7 a.m. to 8 p.m., Tuesday elections 6 a.m. to 8 p.m. A scheduler that derives either the weekday or the hours from a national default is wrong on most of Louisiana's calendar.

Resolved

Each election date carries its own weekday and poll hours as data. Nothing about a Louisiana election is inferred from the state record.

Δ 03Four offices touch one election, and the state owns the machinesEntity resolution
Breaks

The elected clerk of court is chief election officer of the parish and runs election day; the registrar of voters is appointed by the parish governing authority and owns registration and early voting; a parish board of election supervisors counts absentee and early ballots; and the Secretary of State is chief election officer of the state. No one is elected to administer elections as such. Meanwhile title to every voting machine vests in the state, so there is no per-parish equipment table to build — it is one state row, currently mid-procurement.

Resolved

Four distinct entity types per parish with distinct selection methods, and equipment modeled once at state level with a procurement flag rather than 64 times.

Δ 04Unopposed candidates never appear on a ballotStructural
Breaks

Under the majority system a candidate who draws no opponent is declared elected and their name is not printed. A winner can therefore hold office with no ballot line and no vote total at all — three Supreme Court justices this cycle. And a candidate who takes a majority in the first round is elected outright, so the 'general' for that office simply does not occur. A model that expects every officeholder to have a vote count, or every office to appear at the general, is wrong in both directions.

Resolved

Outcomes carry first-class states for elected-unopposed and decided-in-the-primary. Generals are conditional per office, never per date.

Δ 05The state promulgates; it does not certifyNomenclature
Breaks

Louisiana's word for the final act is promulgation, and it runs on a statutory ladder: the parish board files its compiled statement with the clerk by 4 p.m. on the fifth day, mails a copy to the Secretary of State by noon on the sixth, tentative results post by noon on the seventh, and the returns are promulgated by publication in the state's official journal on the fourteenth. A pipeline matching on the word 'certify' misses the event entirely.

Resolved

The certification lexicon carries promulgate, and the 5/6/7/14-day ladder is modeled as distinct events rather than one 'results final' flag.

Δ 06Parishes, police juries, and parish presidentsNomenclature
Breaks

There are no counties. Thirty-eight parishes are governed by a police jury whose members are jurors and whose head is chosen from among them — so those parishes have no separately elected executive at all — while others use a council with an elected parish president, four are consolidated city-parishes, and one is council-manager. A title-based classifier misfiles the legislature and invents an executive that does not exist.

Resolved

Parish records carry a government-form enum; whether an elected executive exists, and what it is called, is derived from that form rather than assumed.

Δ 07The state cycle is odd — 2026 is federal, judicial and localScheduling
Breaks

Governor, every statewide office, both legislative chambers and the parish row offices all elected in 2023 and elect again in 2027. So a midterm crawler finds no state executive and no legislature here. What 2026 does carry: the federal races, district attorneys and district judges on their even-year congressional clock, school boards, the closed-primary offices, and municipal elections on their own charter dates.

Resolved

Louisiana runs a two-track calendar — state and parish on the odd quadrennial, federal and judicial on the even year — with municipal dates held per charter.

Δ 08A November race can end in December, and December starts another oneOrdering
Breaks

Anything short of a majority on November 3 goes to a runoff on Saturday, December 12 — including every U.S. House district under the reverted system. That same December ballot also opens a new contest: the special primary for the 14th Senate district, whose own general falls in January 2027. A runoff date carrying another race's first round breaks any model that treats December as the end of the cycle.

Resolved

Election dates carry a full ballot inventory rather than a single role, so one date can be a runoff for one office and a first round for another.

Federal to levee district

What Louisiana actually elects.

Almost nothing on this ladder is a parish office — the entire courthouse elected in 2023 and elects again in 2027, so 2026 belongs to the federal races, the bench and the school boards.

Returned for too few districts to tabulate — reported as a gap rather than a column of dashes. No demographics on this map, deliberately. ACS is published against the districts as they were drawn in 2023 and keyed by GEOID. Under this plan that key still resolves — to a different area. Joining on it would attach one district's population to another's shape and print it as fact, so the fetcher refuses the join rather than the map guessing.
