Each political party within that area is headed by precinct committee persons who arrange for the caucus meeting on the first Tuesday of April of every even-numbered year. There are approximately 3,000 precincts in Colorado. The precinct caucus is a political meeting of eligible voters, usually held in a home or public place within the precinct. Although anyone can attend a caucus, only registered electors who have resided in the precinct for a least 30 days before the caucus and have been affiliated with the political party for at least two months may vote at the caucus.
Caucuses have an established agenda.
They first elect someone to chair the meeting and someone to record the proceedings. A precinct committee man and a precinct committee woman are elected to represent the precinct on the county central committee of their party. These officers are in charge of fundraising, getting out the vote, notifying voters of the time and place of the county convention or assembly, and planning meetings. Delegates to the county assembly or convention are selected at the precinct caucus. The number of delegates is determined by the county central committee based on the number of electors in the precinct who are affiliated with the party.
