Utah Poll of Record: Spot-On Predictions Solidify NPI as Utah’s Top Pollster

NPI Poll of Record Proves Accurate in Highly Competitive GOP Primaries

PHOENIX (June 27, 2024)- As unofficial results from Utah’s 2024 primaries are finalized, Noble Predictive Insights’ (NPI) poll of record has correctly predicted the outcome of Utah’s GOP Senate and gubernatorial primaries.


This Utah Public Opinion Pulse (UTPOP) poll of record, conducted from June 20–21, 2024, surveyed 432 likely Republican primary voters in Utah, yielding a margin of error of ±4.71%.



In NPI’s poll of record, conducted just days before Election Day, results showed a 20-point lead for Rep. John Curtis over Riverton Mayor Trent Staggs in the GOP Senate primary, with Curtis at 48% and Staggs at 28%. Current unofficial results confirm our prediction – John Curtis wins the primary with 50.1%, and Staggs at 30.9% (as of June 26, 5:00pm) – both numbers well within the poll’s margin of error.

NPI’s poll not only accurately predicted the election results but also provided deep insight into the internal dynamics within Utah’s GOP electorate. Trumpian politics are not as popular in this heavily Mormon state as they are in other red states, and the loss of the Trump-endorsed candidate emphasizes that trend. John Curtis, who is well-known for his more moderate stances, received significant support from Party-first Republicans (60%) while still managing to capture 22% from Trump-first Republicans. Staggs received 55% support from Trump-first GOP voters and 18% from party loyalists. Trump’s endorsement may hold less weight in Utah compared to other states, and when Party-first Republicans unite behind a more moderate candidate like Curtis, they have significant influence on the outcome.


"The value of this poll isn't just in the prediction – it's in the explanation,” said NPI Chief of Research David Byler. “We now know that the Mormon vs non-Mormon split wasn't huge, and that other gaps – like the gender gap or the gap between Trump-first and party-first Republicans – made the difference. We know that if another MAGA politician rises in Utah, their base will likely be in the south. This poll doesn't just tell us what -- it tells us why."



NPI’s poll of record aced the gubernatorial race as well. Our poll showed incumbent Gov. Spencer Cox leading by 13 points at 55% with Phil Lyman at 42%. Current unofficial results confirm our prediction and our precision – Cox wins the gubernatorial primary by 13 points at 56.6% to Lyman’s 43.4% (as of June 26, 5:00pm). Other public polls on this race had Cox leading by at least 40 points, including the only other poll conducted in the month of June.

"Our poll was accurate in both races, but the Cox vs Lyman projection is a particular point of pride. Almost nobody in the national or state media was watching this race. Virtually everyone else who was paying attention overestimated Cox. But we got it right. We were careful about methods, our sample, weighting, analysis – and it really paid off," said David Byler.


The Trump/party loyalty divide was particularly pronounced in this race. Trump-first Republicans clearly favored Phil Lyman who received 80% of their support compared to Cox’s 19%. Party-first Republicans were slightly less unified with 70% backing Cox and 28% supporting Lyman.  


Historically, Utah’s political landscape has been shaped by political figures like Mitt Romney who represented more moderate Republican stances. However, the pro-Trump wing is growing in strength, as evidenced by the significant support for candidates explicitly aligned with Trump. Despite this shift, Spencer Cox's victory in the election underscores the continued influence of party loyalists and moderates in Utah's electoral outcomes.


The wrap-up of the 2024 primary election in Utah once again proves the value of having a pollster who knows the ins and outs of the local electorate and sound methodology with a proven track record for accuracy. This NPI poll of record – the second of the 2024 election cycle – marks a continuation of successes from our Nevada GOP primary poll of record and the previous election cycle. NPI was ranked the #11 most accurate pollster and #4 for lowest average bias in the nation (#1 in the Southwest region for both) in the 2021-22 election cycle by FiveThirtyEight.


“As long as we’re around, Utahns and key decision-makers in the state will not be deprived of consistent and accurate public opinion data,” said Mike Noble, NPI Founder & CEO.
