Bingham County voters delivered a sharp rebuke to incumbent Coroner Jimmy Roberts in Tuesday’s Republican primary, replacing him with political newcomer Scott O. Tweedy by a margin of nearly three to one. In a separate race on the same ballot, incumbent Assessor Donovan Harrington held his seat against a challenger.

Coroner: a rare incumbent loss

Tweedy took 4,723 votes, or 74 percent, against Roberts’s 1,605 votes, or 26 percent. Roberts was elected to the coroner’s office in May 2022 and was running for a second term. The result is the kind of decisive loss that is unusual for an unopposed incumbent in a low-profile county office, and it leaves the office in new hands for the first time since 2022.

No Democratic candidate filed for the Bingham County coroner race, so the primary effectively decides the seat. Tweedy is expected to take office in January.

Assessor: a clearer win

In the assessor’s race, Harrington took 4,192 votes, or 69 percent, against Jonathan Stimens’s 1,862 votes, or 30 percent. The result keeps Harrington in the county’s top property-valuation post. As with the coroner’s race, there is no November opponent.

Bingham County’s primary night reflected a broader pattern across eastern Idaho on Tuesday: voters were willing to remove incumbents in some down-ballot races while returning others by comfortable margins, with no clear ideological throughline.
