Why do Iowans caucus?

In presidential years, the caucus’ most popular feature is the presidential preference poll. This is where hundreds of thousands of Iowans formally begin the presidential nominating process for both major national parties. 

Both parties also conduct important business on caucus night. The precinct caucus is the ultimate grassroots function of Iowa politics. It is where one can be elected to a leadership position in your county party, and it is also where changes to the party’s platform are introduced.
