Third column names the leading third-party or independent finisher. Source · MIT Election Lab · ICPSR · VEST (precinct-level 2024). Swing · margin change from the prior cycle. vs U.S. · margin relative to the national result that year. † 2004, 2012 sub-county results are estimated: the source's block-level detail for these cycles was unreliable — either county/municipality-level consolidated reporting (COVID-era) or a precinct-to-block allocation that misplaced votes — so the figures are allocated from the constituent county totals in proportion to the place and scaled to certified totals.

RTravis IsmayState House · 28B
State legislative officeholder from OpenStates nightly current-legislator data.
District 28B recorded a 64.5-point Republican presidential margin in 2024, placing it among the state's most one-sided constituencies. Its small population of roughly 13,000 reflects the sparsely settled rural character typical of western South Dakota.
Across the recorded series it reached a Democratic high of 36.8 points in 1912 and a Republican high of 65.4 points in 2016. Between 2020 and 2024 the district moved 1.8 points toward the Republican candidate; the 2024 margin was 64.7 points.
A population of 13,256, a 90% non-Hispanic-white share, and a median household income of $73,735 describe the district. The district's voting pattern over the last decade is most similar to that of State House District 34 and State House District 33.

Political twins — state-house districts
The state-house 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.
