U.S. House
Each result reflects the U.S. House district as it was drawn for that election; redistricting has redrawn these lines over time, so they can differ from the current 120th-Congress district shown on the map above.
Stretching from the San Antonio suburbs to El Paso's doorstep, TX-23 covers more border miles than any other congressional district and has shifted 20+ points toward Republicans over the past decade as Latino voter preferences realigned.
Across the recorded series it reached a Democratic high of 63.7 points in 1932 and a Republican high of 41.0 points in 1972. Between 2020 and 2024 the district moved 7.7 points toward the Republican candidate; the 2024 margin was 14.8 points.
A population of 766,972, a 31% non-Hispanic-white share, and a median household income of $77,875 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 27 and Congressional District 35.
The congressional districts whose fingerprint — 2000–2024 trajectory, demographics, ancestry, religion — sits closest to this one, and why.
Twin score (0–100) = weighted cosine between tier-standardized fingerprints: presidential margins 2000–2024 with 12-yr trend and elasticity, ACS income, age, education, population and race, top reported ancestries, and religious adherence — chips name the closest-shared dimensions and the widest gap.
