HOW A DEMOCRATIC CAUCUS WORKS

1. Voters at each caucus divide into groups according to candidate preference. A chairmandetermines the quorum each group needs to elect county convention delegates, (15 percent of total attendance).

2. The chairman records the size of each preference group. Those lacking quorums may join other groups. (If one candidate has 85 percent or more of the caucus vote, he is automatically awarded all the delegates.)

3. The chairman informs each group how many delegates it may select. This number is in proportion to the size of the group: Larger groups select more delegates.

4. The chairman informs county Democratic headquarters and state Democratic headquarters how big each preference group is and how many delegates each will elect.

5. The groups elect delegates and alternates, then report their selections and candidate preference to the chairman.

6. The caucus ratifies the election of all the delegates.

HOW A REPUBLICAN CAUCUS WORKS

1. A secret straw vote is held to determine candidate preference. This is a popularity contest, not a step that leads to delegate selection.

2. Results are reported to the News Election Service and state Republican headquarters.

3. The caucus allocates county convention delegates to each candidate. Usually this reflects the preference vote, but it is not directly tied to it.

4. Republicans do not require a 15 percent quorum to qualify for delegates.
