Iowa Caucuses 101

For all the media attention on the Iowa caucuses, my bet is that it's unclear to most people just how the Iowa caucuses work. Even to a lot of Iowans it's a mystery.

"How many delegates does each candidate get?" a diner asked Gwen, of Gwen's Diner in Lisbon, Iowa.

Gwen scratched her head. "I'm not really sure," she said. "Somebody just tells you*."

So for those of you looking for the quick-and-dirty run down of caucusing, here's a primer.

Both Republicans and Democrats caucus for their candidates on the same night, sometimes in the same place--a public building like a school or library, or someone's home.

Democrats show their support by standing in a group with other people who endorse their candidate. If their candidate doesn't have a big enough proportion of supporters, they can either go stand with another group or remain undecided. Caucus-goers have an opportunity to discuss their choices and try to persuade others.

In contrast, Republicans do a straw poll, writing their choices on a slip of paper.

At the end of the process, candidates with enough supporters elect delegates to represent them at the county. The number of delegates each precinct can send varies from one to eight.

Eventually, delegates will go on to the party conventions in the summer. Of course, by that time some of the candidates may have dropped out of the race, or delegates may have changed their support, which means that candidates selected in January aren't necessarily Iowa's choice at the party conventions in the summer.

Instead, the caucuses simply give top candidates a boost as they go into the New Hampshire primary. It also makes a media event: with a contest, a winner and a loser, the morass of campaigns turns into a story.
