The correct answer is: <u>Caucus.</u>
Caucus refers to a group of members of the same political party that gather together to make decisions for their party. There are many types of caucuses, one of the most important caucuses is the Presidential nominating caucus.
Presidential nominating caucuses at state level:
Members of each party gather together in local meetings to debate and choose who they prefer to be their party's presidential candidates. Participants speak on behalf of their candidate in order to convince others to join them, people can change from one candidate to another before the final count, the candidate that gets more supporters will receive more delegate votes from that state and then they are tabulated.
Even though everyone that is affiliated to a political party can participate in a caucus, there are fewer participants than in the primary because it is a longer process.
