BOISE, Idaho (AP) — Idaho Democrats are considering abandoning their presidential caucus in favor of a primary.

The Idaho Statesman reports that delegates on Saturday approved a resolution endorsing the switch at the party's state convention and instructed the state committee to explore options for a selection process on par with a primary.

The move toward an election format change comes after huge turnout at the party's March caucus caused significant delays and other logistical problems.

More than 9,000 people came to the Ada County venue and after up to two-hour delays to enter the caucus, hundreds of people left without casting a vote. Idaho Republicans switched to a primary format this year after pushing through the Legislature a move to hold a stand-alone presidential primary in March.
