State-level election results

—

Margin is the Republican candidate's share minus the Democrat's, of all votes cast in the race. "Shift" compares a county with the previous race for the same office (both Railroad Commission seats count as one office). In 2006 the governor's race had two strong independents; counties they won are purple. The 2000 and 2012 unexpired-term Railroad Commission races, and several Supreme Court races, had no Democrat on the ballot. Each Supreme Court seat is compared with its own previous election, usually six years earlier. The source files had El Paso and Ellis counties swapped in 2014 and 2018 and a handful of single-county typos; all were corrected against the official returns. One error is in the certified canvass itself (Kaufman County, 2010 attorney general) and is flagged on the map. Results: Texas Secretary of State canvass via OpenElections (2000–2018), MIT Election Data + Science Lab (2020–2022), CivicAPI for 2024 and the official canvass for 2020; county totals were checked against the Legislative Council's official returns for 2012–2022. Presidential results: the Secretary of State's official county returns (2000–2016) and CivicAPI (2020 and 2024, whose statewide totals equal the certified canvass); every county was compared with the Legislative Council's returns for 2012–2024 and differs by at most a few hundred votes (Brazos 2012 and Williamson 2020 by about 800 and 1,500, from the Council's precinct allocation). Write-in candidates are combined. 2026 results come from the Texas Secretary of State's election-night results and are unofficial until canvassed. Turnout is ballots cast divided by registered voters, for the whole November ballot: county figures from the Secretary of State's county turnout history (2000–2022) and the Legislative Council's precinct data (2024, which runs about 0.6% above the state's count); statewide figures are the state's official numbers. Coleman County has no 2008 figure.
