Idaho voters are casting ballots Tuesday to determine who will represent the state in the U.S. Senate for the next six years. The race pits longtime Republican incumbent James Risch against independent candidate Todd Achilles, a former Democratic state senator who left the party to run as an independent.
Risch, who chairs the Senate Foreign Relations Committee, is seeking his fourth term. He first won election to the Senate in 2008 and has since become a prominent voice on foreign policy and defense issues. In the GOP primary earlier this year, Risch secured roughly two-thirds of the vote, cementing his status as the party's standard-bearer.
Idaho is one of three states this cycle where the Democratic Senate nominee has stepped aside in favor of an independent candidate, alongside Nebraska and South Dakota. In neighboring Montana, independent Seth Bodnar is considered competitive, but the Democratic nominee remains on the ballot there. This unusual dynamic underscores the challenges Democrats face in deep-red states and has reshaped the contours of the race in Idaho.
Achilles, an Army veteran and college professor, served as a Democrat in the Idaho state Senate before resigning in 2025 to launch an independent gubernatorial bid. His campaign has focused on issues such as veterans' affairs, education, and government accountability, but he faces steep odds in a state that has not elected a Democrat to the Senate since 1992.
Political analysts note that Risch's position as Foreign Relations Committee chair gives him significant clout in Washington, particularly on matters of international diplomacy and national security. His campaign has emphasized his seniority and ability to deliver for Idaho, including on public lands and agricultural issues.
Achilles, meanwhile, has sought to position himself as a pragmatic alternative, criticizing partisan gridlock and promising to work across the aisle. However, his path to victory remains narrow, as Idaho's electorate has consistently favored Republicans in recent statewide contests.
Polls close at 10 p.m. EST, with results expected to come in quickly thereafter. The outcome will be closely watched not only for the immediate Senate balance but also for what it signals about the broader political landscape in the 2026 midterms. While Idaho is not considered a battleground, the race offers a test of independent candidates' appeal in conservative states.
For those following election night returns, Idaho's results will be a data point in the larger national picture, which includes critical races in other states. The night's outcomes could also shape the 2028 presidential field, as both parties assess their strengths and weaknesses.
In the closing days of the campaign, Risch has focused on his record and experience, while Achilles has hammered on themes of independence and reform. Voter turnout will be key, especially in rural areas where Risch has traditionally performed well.
As the results come in, attention will turn to whether Risch can replicate his previous margins and whether Achilles can make inroads with moderate voters. The race also carries implications for the Senate's balance of power, though Idaho's seat is widely expected to remain in Republican hands.
