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. Third-party votes in 2012 are allocated from certified county totals by this place's share of each county's two-party vote — that cycle's precinct source records two-party splits. † 2004 sub-county results are estimated: the source's block-level detail for this cycle 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.

Assembly District 21 delivered a 35-point Republican presidential margin in 2024, making it an outlier in a state that has trended competitive statewide. Its rural or exurban character anchors a voter base that consistently diverges from Nevada's urban centers.
Across the recorded series it reached a Democratic high of 12.5 points in 2008 and a Republican high of 1.8 points in 2004. Between 2020 and 2024 the district moved 4.8 points toward the Republican candidate; the 2024 margin was 1.7 points.
A population of 74,536, a 53% non-Hispanic-white share, and a median household income of $87,455 describe the district. The district's voting pattern over the last decade is most similar to that of Assembly District 5 and Assembly District 41.
