Background

Swensen grew up in Twin Falls, where his family operated a grocery business he describes, on his campaign website, as having served Idaho families for nearly a century. He graduated as valedictorian from Twin Falls High School. He then earned a degree in Philosophy from Brigham Young University and a law degree, graduating cum laude, from Thomas Jefferson School of Law in San Diego.

Policy Positions

Swensen’s campaign centers on three themes drawn from his campaign website: economic development and small business support, public safety and law enforcement, and tax reduction. On the economy, his campaign states: “I’ll fight to support our small businesses, make housing affordable, and bring in good-paying jobs that keep our rural way of life strong.” On public safety, his campaign messaging emphasizes backing law enforcement and border security, stating he will “secure our borders to keep drugs out.” On taxes, he frames his position as fiscal restraint: “I’ll work to lower taxes, ease the cost of living, and make sure our tax dollars are spent wisely.”

At a candidate forum held February 26, 2026 at the Gas Lamp on Third in Twin Falls, Swensen participated alongside other legislative candidates ahead of the primary, as covered by KMVT.
