David Roth, the Democratic nominee in Idaho’s U.S. Senate race, ended his campaign Tuesday evening, stepping aside and effectively consolidating opposition to Republican incumbent Sen. Jim Risch behind independent candidate Todd Achilles.

Roth, an Idaho Falls consultant, won the Democratic primary in May but struggled to gain traction financially. Federal Election Commission data showed his campaign raised roughly $8,600 this cycle — a stark contrast to Achilles’ $692,000 and Risch’s more than $3.3 million.

Pressure to Step Aside

The move came after weeks of mounting pressure from within Democratic circles. Former Democratic Rep. Larry LaRocco publicly called on Roth to withdraw, pointing to a similar situation in Nebraska where Democratic candidate Cindy Burbank stepped down in favor of independent Dan Osborn.

Ada County Democrats formalized that pressure in a letter to Roth on July 8, setting an August 12 deadline for him to raise $50,000 and submit a credible campaign plan. The county party’s executive committee had signaled it would consider backing Achilles if Roth failed to meet those benchmarks.

Policy Differences Acknowledged

Roth did not leave quietly on the question of ideology. He cited single-payer health care and housing investment as areas where he and Achilles part ways, characterizing the independent as occupying more moderate ground. Roth said he intends to redirect his energy toward helping Democrats compete in down-ballot races across Idaho.

Roth had met with Achilles before the Democratic primary, suggesting the possibility of a strategic arrangement had been discussed well in advance of Tuesday’s announcement.

Achilles as the Remaining Challenger

With Roth’s exit, Achilles stands as the only well-funded alternative to Risch in the general election. While his fundraising trails Risch’s by a wide margin, his campaign infrastructure is far stronger than what most independent Senate bids in Idaho have historically managed.

Risch, a five-term senator and senior member of the Senate Foreign Relations Committee, remains a heavy favorite. Idaho has not sent a Democrat to the U.S. Senate in decades, and the state’s political landscape tilts heavily Republican.

Achilles’ path, if one exists, runs through consolidating voters skeptical of Risch across party lines — a strategy that becomes more plausible without a Democrat splitting that vote. Whether that coalition can reach competitive numbers against Risch’s financial and institutional advantages is the central question heading into the fall campaign.

Idaho’s Senate contest is one of several races drawing unusual attention this cycle. Election integrity measures and candidate activity have already prompted legal scrutiny in the state, adding to the elevated profile of Idaho’s 2026 ballot.
