Utah has gradually become more politically purple, due to a tech-sector workforce and Mormons not always being keen on Trump.

The claim has two parts: (a) over recent cycles Utah's presidential or partisan margins have moved toward Democrats (less strongly Republican than before), and (b) this is linked to tech-sector in-migration and Latter-day Saint coolness toward Trump. True: election results (e.g., Republican presidential margins of 2012, 2016, 2020, 2024 relative to the nation) show a gradual narrowing of the Republican advantage, and credible analyses tie it to both factors. Mostly true: the trend is real but irregular, or only one cause is well documented while the other is plausible. Mixed: the trend appears only on some measures (e.g., only relative to 2012 Romney, or 2024 results moving back toward Republicans), or only partly holds. Mostly false: Utah remains overwhelmingly Republican with no sustained trend and the claim rests on a single anomalous cycle (e.g., 2016 McMullin) or on Mormon distaste for Trump without any real shift toward Democrats. False: Utah's margins have moved toward Republicans or stayed flat across the relevant cycles.

   “Donald Trump carried it in 2024 by 21.6 points, 20.1 points more Republican than the nation.”

3. E3 Study: GOP losing ground among Latter-day Saints Axios · 31 March 2026

   “Republicans had a 52% advantage over Democrats among surveyed Latter-day Saints from 2007 to 2009; that shrunk to a 33% advantage in the 2023–2025 period.”

4. E4 Final Utah results: Trump grew support by 5% with late breaking ballots Deseret News · 25 November 2024

   “beating his Democratic opponent by 21.6 percentage points with 59.4% of the vote, compared to his 20.5-point win in 2020 with 58.2% of the vote.”

E1 gives Utah's 2012 Republican margin as R+48.0 when the national margin was D+3.9. E2 and E4 put Trump's 2024 margin at 21.6 points, and E2 says this was 20.1 points more Republican than the nation. That is a large narrowing since 2012. But E4 also shows Trump's margin grew from 20.5 points in 2020 to 21.6 in 2024, so the most recent cycle moved back toward Republicans in raw margin. The resolution criteria list this as a reason for a mixed verdict. On the causes, E3 documents a shrinking Republican advantage among Latter-day Saints (52 points to 33). No evidence addresses the tech-sector workforce, and none covers 2016, so the evidence cannot show whether the trend was gradual.
