Should the US Nix Caucuses and Use Only Primaries?

A caucus () is a meeting of supporters or members of a political party or movement, especially in the United States. The exact definition varies among political cultures.

The Iowa caucuses are an electoral event in which residents of the U.S. state of Iowa meet in precinct caucuses in all of Iowa's 1784 precincts and elect delegates to the corresponding county conventions. There are 99 counties in Iowa and thus 99 conventions. These county conventions then select delegates for both Iowa's Congressional District Convention and the State Convention, which eventually choose the delegates for the presidential nominating conventions (the national conventions).

The Iowa caucuses are noteworthy for the amount of media attention they receive during U.S. presidential election years: Since 1972, the Iowa caucuses have been the first major electoral event of the nominating process for President of the United States. Although only about one percent of the nation's delegates are chosen by the Iowa State Convention, the Iowa caucuses have served as an early indication of which candidates for president might win the nomination of their political party at that party's national convention.
