Answer:
The event described is called a caucus
Step-by-step explanation:
In Iowa, registered members of a political party gather together on a pre-determined night in January of a presidential election year.
These registered members participate in a process known as a caucus.
During the caucus, members of the political party discuss and debate the merits of different candidates.
Members may split into groups or "caucuses" based on their candidate preference.
Members may also engage in a voting process to determine the candidate they believe should be the nominee for their party.
The results of the caucus are used to allocate delegates to the party's national convention, which formally selects the party's nominee for president.
Overall, a caucus is a process used in some states in the United States to select a political party's nominee for president. It involves registered members of the party gathering together to discuss, debate, and vote on the candidate they believe should represent the party in the general election
