Utah’s 2026 legislative elections are months away, but the battlefield is already taking shape.
Today, Utah Political Watch launches district-by-district race ratings for every Utah House and Senate seat on the 2026 ballot. We analyzed eight statewide elections from 2016 to 2024, plus legislative results from 2022 and 2024, to build the most detailed independent assessment of Utah’s legislative map you can get.
In short, Republicans are dominant, but not everywhere. And in a state this red, even small shifts can matter.
How the ratings work
Every district gets two ratings.
First, the Likely Outcome, reflects historical two-party vote share in that district. A district rated Safe Republican is one where the GOP candidate has consistently won by wide margins. A district rated Lean Republican is one where Republicans win, but the margins are tighter. Toss-up means neither party has a consistent edge.
Second, the Utah Competitiveness Index (UCI) measures how far a district sits relative to Utah's statewide Republican baseline of approximately 64.5%—meaning the average Utah legislative district votes about 65% Republican in a two-party race. The UCI tells you which districts are competitive by Utah standards. A district can be Lean Republican on Likely Outcome yet post a negative UCI because it’s more Democratic than the typical Utah district, even if Republicans still prevail.
Think of it this way: Likely Outcome suggests who is probably going to win. The UCI tells you which races are worth watching.
What the Senate map looks like
Fifteen Utah Senate seats are on the 2026 ballot. On paper, the map is not particularly competitive this year.
Three seats rate as Safe Republican (SD1, SD21, SD28). Six more are Likely Republican. On the Democratic side, two seats rate Safe and one rates Likely—all in Salt Lake County.
The races to watch are SD5 and SD19. Both rate as Lean Republican—meaning Republicans are favored, but the margins are thin enough that a strong campaign or a shift in the political environment could make things interesting. SD5 is an open seat, and in 2024 Trump managed just 55.9% of the two-party vote there, not exactly a comfortable margin for a party that usually dominates Utah.
The House map is bigger—and more complicated
Twenty-eight House districts rate as Safe Republican. Seventeen more rate as Likely Republican. On the other end, five are rated as Likely Democratic and five as Safe Democratic—all clustered in Salt Lake County.
Twelve districts are Lean Republican, meaning the GOP is favored but not comfortably. Six districts rate as true toss-ups, with no clear historical edge for either party.
Utah Political Watch subscribers get the complete 2026 Utah Legislature ratings—all 15 Senate districts plus all 75 House districts, each with presidential results, voter registration breakdowns, historical race results, and the Utah Competitiveness Index for every seat. It’s the most detailed independent look at Utah’s 2026 legislative map anywhere.
