Two-way race: turnout matters Draft: awaiting review
Kevin Marsh D
Kevin Marsh is the only non-Republican on the ballot, so this is a two-way race and turnout is what matters. Open seat: Rep. Jack Nelsen (R) is not on the ballot. The seat was decided by 84 votes in 2022 and 3.1 points in 2024. District lines were the same in 2022 and 2024 (the post-2020-census map), so both results compare directly.
