What’s changed about the Iowa Caucuses?

Our new Iowa Democratic Caucuses will consist of two parts:

One part will be the mail-in expression of Presidential preference. Iowa Democrats will be able to request a presidential preference card through the mail or online. Please use the links above. The last day to request a preference card is February 19, 2024.

The other part will be our in-person precinct caucuses which will be held in person on January 15, 2024 at 7:00 p.m. The in-person precinct caucuses are when we will conduct traditional party business. We will elect unbound delegates and alternate delegates to county conventions, elect county central committee members and discuss platform resolutions that can be shared at county conventions. No Presidential preference will be taken at the in-person precinct caucuses. The results of the mail-in Presidential preference will be released on March 5, 2024.

County Conventions: March 23, 2024
District Conventions: May 4, 2024
