Caucuses are meetings of members of a political party or group to discuss and decide on candidates or policies. They often take place at local, state, or national levels and can involve debates, discussions, and voting. Caucuses are a key part of the electoral process in some regions, particularly in the United States. In a caucus, participants gather to express their preferences for candidates, often through a show of hands or by physically moving to different areas. This process helps to gauge support and can influence the selection of delegates for events like primaries or national conventions.
