Republican Sen. Codi Galloway on Monday withdrew her 2026 election filing in District 15, according to information on VoteIdaho.gov.

Democrat Nancy Gregory, a 24-year Boise school trustee, is running for the seat.

District 15 is a swing district with one Democrat and two Republican incumbents.

Another Republican also dropped out of the race. Challenger Gary Alfred Butts filed on Wednesday but withdrew his candidacy on Friday, according to VoteIdaho.gov.

That leaves two candidates.

Gregory will face Republican Desi Burbank in November. There will be no contested primary elections for the Senate seat.

Burbank does not appear to have a campaign website or election history in Idaho.

In an October interview with EdNews, Gregory said west Boise voters are looking for a different voice.

“Public schools are working very hard to do a good job for their communities,” she said. “The Legislature seems to be more intent on making that more difficult than more reliable and steady and supported.”

Galloway did not immediately respond to an interview request on Tuesday morning.
