Where this data comes from

Candidates and races as certified

Taken from the Texas Secretary of State’s certified ballot reports for the November 3, 2026 general election in Tarrant County, dated September 7, 2026, in Dallas County, dated September 9, 2026, and in Collin County, dated September 10, 2026. Race names, candidate names, and party labels are as printed in those reports. Open the Tarrant County PDF, the Dallas County PDF, or the Collin County PDF — all three are checked into this site under sources/.

Tarrant Appraisal District board

Three at-large seats that appear on no certification report, because the appraisal district runs its own election. The candidates are those on the Tarrant County Elections qualified-candidate list; the order they appear in is the one TAD drew by lot on August 25, 2026 under Election Code §52.094; and each name is spelled as the county’s sample ballot prints it, which is not always how the filing list spelled it. The office is nonpartisan by law, so no source prints a party and none is shown. Open the qualified-candidate list or the ballot drawing result — both are checked into this site under sources/ — or look up your own sample ballot at Tarrant County.

1,771 voting precincts

707 in Tarrant County, 791 in Dallas County, and 273 in Collin County. Precinct boundaries, and the congressional, legislative, SBOE, commissioner, and JP districts attached to each one, come from each county’s precinct layer. The address lookup tests your coordinate against these polygons in your own browser, one county’s file at a time. Tarrant — Tarrant County GIS, Voting Precinct service, read here as data/precincts.geojson. Dallas — the PRCNT_791 precinct layer this file was pulled from, read here as data/dallas-precincts.geojson; its FIRST_DIST* district fields were renamed to match Tarrant’s. Collin — the Voting_Precincts layer this file was pulled from, read here as data/collin-precincts.geojson; its district fields were renamed the same way, so one lookup can read all three.

What each office does

Plain-language summaries written for this guide, not quoted from any official source. Each one links to the constitutional or statutory provision it is based on, so you can read the law yourself rather than take the summary’s word for it. Summaries cover most but not all races; a race with no summary shows only its certified title. Open data/offices.json — the descriptions and their law links are checked into this site.
