Starting in 2024, Republicans in Idaho will have to attend caucuses to make their presidential picks. Presidential caucuses are planned for March 2, putting them near the front of the national presidential selection process. Instead of voting in a Tuesday primary at traditional polling places, people wanting to participate in the caucuses will need to attend a Saturday meeting of local Republicans. In Idaho, the GOP caucuses will have a single round of voting for presidential candidates. For a primary election, an elector may change their political party affiliation or become “unaffiliated” by filing a signed form with the county clerk no later than 2/17/24. (Deadline is postmarked by this date for mailed paper applications, 5 p.m. for paper applications handed in to the county clerk’s office, or until midnight for online applications).
