In even-numbered years, each political party holds a separate caucus in each precinct to select delegates to the party’s county convention. Please contact the party of your choice for more information.

Presidential Caucuses

In Iowa, the office of President (and Vice President) of the United States is only on the ballot for the General Election; Iowa does not have a Presidential Primary Election. The Democratic and Republican parties hold caucuses to determine delegates for the county, and ultimately, the district, state and national conventions. The parties’ national conventions then select their parties’ nominees for President and Vice President.


Per the Code of Iowa, the state central committees of the parties set the date of the caucus. By law, caucus must be held "at least eight days earlier than the scheduled date for any meeting, caucus, or primary which constitutes the first determining stage of the presidential nominating process in any other state, territory, or any other group which has the authority to select delegates in the presidential nomination." Caucus must be scheduled no later than the fourth Monday in February.
