Primary Elections: Frequently Asked Questions

A primary is an election that takes place within each official political party. No one is elected in a primary election. Instead, voters affiliated with political parties will select their party's candidates for the November 8 general election.

Only the two full-status parties - Democrats and Republicans - hold primaries, and only voters who register with a party may vote in the primary. Voters may change party at any time including Election Day.

Independents or candidates of other parties may file for the November 8 general election by petition during the general election filing period: August 1-19 for state and federal offices and August 8-31 for county offices.

Voters can only participate in one party's primary.

Oversimplified Example: Primary and General Election Ballots 

 Primary election: choose one party's primary
or the other; cannot vote a split ticket.
Only Democrats and Republicans on ballot.

General election: Everyone gets the same ballot. More parties on ballot, you can split your ticket.  
demprimaryexample  gopprimaryexample  generalexample 

If you are registered to vote as a Democrat, for example, your vote in the primary election will help choose the Democratic Party's nominees for various offices. Since you, as a registered Democrat, are selecting your party's candidate to run against candidates from other parties in the general election, you will be given a ballot with only Democratic candidates to choose from. You will not see the names of any Republican or other candidates on your primary election ballot.

In the general election, which decides who will actually fill the offices, all voters get ballots listing all of the candidates.

Can an independent vote in a primary? 

Yes and no. You can walk IN as an independent, but you can't walk OUT as an independent. You have to declare affiliation as a Democrat or Republican before you vote.

Can I vote for a Republican for one office and a Democrat for another? 

In a general election, yes. In a primary election, no.

Can I write in a candidate of one party in the other party's primary? 

Yes, but the party primaries are separate contests. In the example above, if you vote in the Democratic primary and write in Abe Lincoln, that will be counted as a Democratic primary vote for Lincoln, but it will not be added to Lincoln's Republican primary total. Candidates can only accept the nomination of one party.

I've been hearing that some nominations might go to a convention. How does that work?  

Iowa law requires a candidate to win 35% of the primary vote to be nominated. If no candidate wins 35%, a party convention decides the nomination.

  • Statewide office or US Senate: State convention, delegates elected at county conventions
  • US Representative: Congressional district convention, delegates elected at county conventions
  • County office: County convention, delegates elected at caucuses
  • Legislative seats: County central committee members within the district, elected at caucuses
