Heading into the election, the incumbent is Jim Risch (Republican), who was first elected in 2008.
A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. In Idaho, parties decide who may vote in their primaries.[1] As of October 2025, the Democratic Party allows unaffiliated voters to vote in its primary, while the Republican Party only allows voters registered with its party to vote in its primary. Unaffiliated voters can choose to affiliate with a party on Election Day.[2][3]

Submitted Biography: "Idaho deserves leadership rooted in real life - not politics. I am Josh Roy - husband, father, and community-first leader - running for U.S. Senate to put Idaho families and small businesses first. Leadership that works as hard as Idaho does.I admit I have no experience as an elected official. I am running for office while working a high pressure, 50 hour-a-week job in a pulp mill, and raising a family. I recognize this election as a unique opportunity. It is time for a fresh perspective in Washington. It is time for a non-career politician to serve. We need someone who is still grounded in the struggles of everyday citizens. I am going to Washington to fight the regulations that vex the common man. I will fight to defend the needs of the citizens of Idaho for everyday livability. I have extensive professional experience making painful, high stake decisions. Pulp mills are extremely difficult to staff and operate. Downtime cost's often run past $50,000 per day, resulting in very high stress environments. I will bring this leadership experience to the US Senate. If elected I will be the only member of the senate with 20 years heavy industrial experience. I will help the citizens of Idaho rebuild our nation. We need a complete economic rejuvination from harvesting and mining through to the finished products. Very few members of congress can feel at home at a farm, mine, smelter, rolling mill, sawmill, steel mill or machine shop."
