Data layers
Nine layers put the political map on the globe. Here is what each one shows, where it comes from, its licence and how fresh it is.
Open Data Layers on the left rail ([). Layers are grouped into Votes, People, Places, Boundaries and Media. Each row shows its source and licence under the name, and has an on/off switch. Some layers add chips (small buttons) for colour modes or sub-types.

Colour modes
The precinct layers share one colour mode. 2024 shades by the presidential margin. Lean shades by the primary-ballot split. Turnout shades by the share of registered voters who voted. Hispanic, Asian, Black and White shade by share of voting-age population. Spanish surname shades by the share of registered voters with a Spanish surname. Statewide files carry 2024, lean, turnout and Spanish surname. Other modes leave statewide precincts on the 2024 ramp.
Live: early voting & results
- Group
- Votes
- Shows
- Every Texas county shaded by the share of its registered voters who have voted so far, from the Secretary of State's daily early-voting file (19–30 October 2026). On election night (3 November) counties take the leader's party as they report, with precincts reporting; the Precinct results chip paints the Dallas, Tarrant, Denton and Rockwall precincts by their own leader. A pulsing teal-and-gold ring marks a county edition with a live feed. The feed is checked every 60 seconds while the layer or a live card is open.
- Click
- Opens the county card, which leads with a LIVE section: the tally, the share of registered voters, in person and by mail, the change since the day before and a daily sparkline; on election night the top contests with bars and precincts reporting. Where nothing is live, the card shows the last results, when polls close and the official results page.
