Let’s be honest here. If you don’t live in a state that still uses the caucus system, how much do you really know about it? Though the caucus system used to be the dominant system in the US for choosing party candidates in the presidential nomination process, that is no longer the case.
A caucus is more of a discussion, where showing open support of a candidate is copacetic and votes for presidential nominees are cast at the caucus meeting. In a primary, voters go to a polling place, vote, and that’s it. The bottom line between a primary and a caucus is that state governments run primaries, and state parties are in charge of caucuses. There are many reasons that around three-fourths of state parties have moved towards the primary system rather that the caucus system, but most believe that these states have moved towards primaries primarily (haha) because the state pays for it. There are always pros and cons, but we all know that money motivates.
