The Democratic caucus in Ada County finally kicked off around 9 p.m., approximately two hours late, because of the thousands of people who showed up to take part.
Caucuses across the state were expected to close the doors and begin the process of selecting a presidential nominee at 7 p.m. MDT. But the line for the Ada County caucuses in downtown Boise had already wrapped around three city blocks an hour before the event was supposed to begin, forcing officials to delay the start time.
Organizers had urged people to pre-register for the caucus online, and several thousand did so. The Idaho Democratic Party doesn't require ID or proof of address to participate, but caucus-goers must sign a document stating they are eligible to vote in the upcoming Nov. 8 general election.
