Texas
254 counties, 5,533 governments, a runoff that just unseated a 24-year senator — and the map that started the national wave, settled by summary reversal.
How did a four-term senator lose without losing an election?
State deltas
Every state has hair. Here is Texas'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.
HB 4's five-seat redraw launched the national mid-decade era. A three-judge panel enjoined it as a racial gerrymander on November 18; the Supreme Court stayed the ruling by December 4 and summarily reversed on the merits April 27. Any model that froze on the injunction — or the 2021 lines — ran the wrong geography for the primary.
Map versions carry the full litigation timeline as dated events. The 2025 map is marked settled-for-cycle; the 2021 map is archived, never joined.
Nominations require a majority, so March is often just the first round — and May belongs to a smaller, hotter electorate. This year the system unseated a four-term senator who won the first round. A plurality-winner model calls races that Texas hasn't finished deciding.
Primary contests carry majority thresholds and runoff linkage. March results render as round one wherever no one clears fifty.
No party registration exists, but voting in a primary stamps the party on your registration certificate, enters the voter file, and locks you out of the other party's runoff — crossing over is a felony. Then it all resets December 31. Affiliation is real, recorded, and annual.
Affiliation is a dated event with a statutory expiry, never a standing attribute. Runoff eligibility is computed from the March participation record.
The county judge presides over the commissioners court — in big counties a pure executive who tries no cases. The Railroad Commission has regulated oil and gas, not trains, since its rail duties left in 2005. Titles here describe history, not function.
Offices map to statutory functions, not names. The 'court' that runs Harris County is indexed as its executive body, and the RRC as the energy regulator it is.
Judge, county and district clerks, and treasurer ride midterms; sheriff, tax assessor-collector, county attorney, and constables ride presidential years; JPs split by place number; DAs vary by judicial district. The constitutional section that set this stagger was repealed in 1999 — cycles persist by inertia, and newly created offices land wherever their first election falls.
Every office carries its observed cycle from the SOS ballots, not a statute that no longer exists. New offices are cycled from their creation date.
Just over half the counties run elections through an appointed elections administrator; the rest split duties between the elected clerk and tax assessor-collector. In 2023 the legislature abolished exactly one county's EA office — the threshold was written as 'over 3.5 million,' which is Harris alone — and built state-takeover provisions at 'over 4 million.' The publisher model is per-county, and one county's was changed by name-shaped statute.
The election authority is county-level data with its statutory basis and effective dates. Harris keys to clerk-plus-assessor since September 2023; 103 vote-center counties still report by home precinct.
2,984 special districts — third most in the nation — do the growth work of unincorporated Texas. New MUDs are launched by developer-controlled confirmation votes and boards elected by a handful of residents; appraisal districts in every county over 75,000 now elect three of nine directors. Whole layers of government exist before the residents do.
Districts carry their franchise state and confirmation history. A MUD created by four voters is modeled as exactly that, with the transition to resident control tracked as it happens.
The Supreme Court hears civil cases; the Court of Criminal Appeals is a separate court of last resort for criminal — nine members each, all elected statewide and partisan, like nearly every Texas judge down to 796 justice courts. The exceptions run the other way: the new statewide 15th Court of Appeals started appointed, and Business Court judges are appointed outright.
Two apex courts are modeled as parallel hierarchies, and selection method is a per-court attribute — elected partisan by default, appointment flagged where the exception lives.
Federal to MUD
What Texas actually elects.
The seats run bottom-heavy here too — and in Texas the bottom is 2,984 districts, some of them created before their voters moved in.
