Caucus Information

Partisan Caucuses

Each political party plans and holds a separate caucus in even numbered years to select delegates to the party's county convention. More attention is drawn to the Iowa Caucuses during presidential election cycles due to Iowa being the first in the nation and Iowa has no Presidential Primary Election.
