States choose whether they want to hold primaries or caucuses. Most states hold primaries but states like Iowa, Louisiana, Minnesota and Maine use the caucus system.
The territories of American Samoa, Guam and the Virgin Islands use the caucus also. All other states and Puerto Rico use primary elections or a combination of the voting formats. Caucus meetings are arranged by either the state or political party to take place at a certain place and time. Caucuses are unique in that they allow participants to openly show support for candidates. Voting is often done by raising hands or breaking into groups according to the candidate participants support.
