Committeepersons

County Chairs and the State Central Committee in Illinois

Party leadership in Illinois is built from the bottom. Each party's primary voters elect committeepersons (one per precinct outside Cook County, one per ward or township inside Cook), and those committeepersons together make up the party's county central committee (10 ILCS 5/7-8(d)). That committee is where the party organizes in each county, and every vote cast on it is weighted by how many of the party's primary ballots were cast in the member's area. The county chair is the chair of that committee, and the state law gives the chair real work, from certifying election judge lists to sitting on some congressional committees.

The exact procedure for electing a county chair, and the rules for choosing members of a party's state central committee, are detailed matters that depend on the Election Code and on each party's own rules. We do not restate them here, because the precise steps should come from the source: your county party, or the Election Code itself on ilga.gov. What follows is the part every committeeperson should understand first, because it is where all of the higher offices draw their strength: who sits on the county committee, how their votes are counted, and why the precinct is the foundation.

For the full picture of the office, see our Illinois precinct committeeperson handbook.

Layer one: the people the primary voters elect

Everything starts at a primary election.

Outside Cook County, each party's primary voters elect one precinct committeeperson per precinct "at the general primary election every 2 years" (10 ILCS 5/7-8(b)). The candidate must be a bona fide resident of the precinct. The most recent general primary was March 17, 2026, and the next is the 2028 general primary. A precinct committeeperson serves "until the date of the primary to be held in the second year after their election."

In Cook County (counties of 2,000,000 or more), no precinct committeepersons are elected. Chicago voters elect a ward committeeperson for each ward, and suburban Cook voters elect a township committeeperson for each township, at the general primary every four years. They serve until the primary in the fourth year after their election (10 ILCS 5/7-8(b)). Precinct captains in Cook are not a statutory office; they are volunteers organized by the ward or township organization.

To get on the primary ballot, a precinct committeeperson needs at least 10 signatures of the party's primary electors in the precinct. Ward committeepersons need 10% to 16% of the party's primary electors in the ward, and township committeepersons need 5% to 8% in the township, with the maximum allowed to be 50 above the minimum where that is greater (10 ILCS 5/7-10(i)).

Two rules can end a term early. A vacancy exists as soon as a precinct committeeperson stops living in the precinct, and they lose the rights and duties of the office right away. And a person who is statutorily ineligible to vote because of a felony conviction cannot hold the position (10 ILCS 5/7-8). Vacancies are filled under your party's rules, usually through the county chair.

Layer two: the county central committee

The county central committee is made up of the party's township, precinct and ward committeepersons in the county (10 ILCS 5/7-8(d)). It is the body through which a party organizes at the county level, and its chair is the person most committeepersons simply call "the county chair."

How the votes are counted

Votes on the county central committee are not one person, one vote. The statute says "each precinct committeeperson shall have one vote for each ballot voted in his precinct by the primary electors of his party at the primary at which he was elected" (7-8(d)). Ward and township committeepersons vote by the ballots cast in their ward or township at the preceding General Assembly primary.

Here is a simple example to show the effect. The numbers are illustrative, not drawn from any real county.

In this example, the committeeperson from Precinct 1 carries more than five times the weight of the committeeperson from Precinct 3. Both hold the same office. The difference is turnout among the party's own primary voters. Our weighted vote explainer walks through more examples.

Why this matters for anything decided above the precinct

Because the committeepersons are the county committee, any decision the county committee makes is shaped by the committeepersons who show up and by the weight each one carries. A committeeperson who wants a say in how the county party is led, and who leads it, gets that say through the committee, and the size of that say comes from precinct turnout.

The same weighting, on other committees

The weighting in 7-8(d) is not limited to the county committee. The Election Code applies the same approach in several places:

• Municipal central committees (7-8(h)).
• Multi-township central committees (7-8(c)).
• Judicial subcircuit committees in counties outside Cook (7-8(g-1)).

Congressional committees are built in two ways. In a congressional district wholly inside one county, the precinct, township and ward committeepersons in that district make up the congressional committee (7-8(e)). Where a district crosses county lines, the committee is made up of the county chairs instead. That is one place where the county chair's seat directly carries the county into a larger body.

What the law asks of the county chair

The county chair is more than a title. Two parts of the Election Code put specific work in the chair's hands.

Election judges. The county board appoints election judges in each precinct from certified lists furnished by the county central committee chairs of the two leading parties: three judges from the first party and two from the second. The statute adds that "the chair of each county central committee shall, insofar as possible, list persons who reside within the precinct" (10 ILCS 5/13-1). A chair cannot know someone in every precinct, which is why most county parties ask their committeepersons to recruit judges.

Congressional committees. As above, in districts that cross county lines, the county chairs make up the congressional committee (7-8(e)).

Vacancies. When a precinct seat opens, it is filled under your party's rules, usually through the county chair.

The state central committee

Each party also has a state central committee, the body that organizes the party statewide. How its members are chosen is set by the Election Code and party rules, and the method is detailed enough that we would rather send you to the source than paraphrase it. If you want to understand how your party's state central committee members reach their seats, and what part your county committee or your primary voters play, ask your county chair, read the Election Code on ilga.gov, or speak with an election attorney.

What we can say plainly is where the chain begins. Every level above the precinct is built, directly or through the county committee, on the committeepersons that primary voters elect, and on how many of those voters turn out.

Questions to ask your county party

If you are a new committeeperson, these questions will tell you how leadership works in your county:

1. When does the county central committee next meet to organize, and how will I be notified?
2. How is the county chair chosen under our party's rules, and when is the next selection?
3. What is my precinct's weighted vote, based on the primary at which I was elected?
4. Does my area also have a municipal, multi-township or judicial subcircuit committee I sit on?
5. Which congressional committee covers my area, and is it made up of committeepersons or county chairs?
6. How does our state central committee get chosen, and where can I read the rules?

Write the answers down. They will change slowly, and the next committeeperson in your precinct will want them.

Know your primary voters, door by door

The one thing a committeeperson can actually move is the number of the party's primary voters who turn out in the precinct. That starts with knowing the precinct well enough to find them.

Map your precinct and keep its history. In Beacon, you load your precinct's walk list onto a map, route the doors, and record each result as you go: contacted, not home, come back later, moved, left literature and the rest, along with a 1 to 5 rating, notes and survey answers. Beacon works offline and syncs when you are back in range, so a dead zone at the end of a cul-de-sac does not cost you the record. A survey question such as "planning to vote in the primary: yes, no, unsure" records each answer, survey responses export to CSV when you want to work through them, and analytics show how much of the precinct you have actually covered.

Party organizations can go further. Territory management lets a township or county party assign precincts to committeepersons and see coverage across all of them, with unlimited canvassers on every plan. Our post on running 100 precincts from one map shows how that looks across a county.

FAQ

Who sits on the county central committee in Illinois? The party's township, precinct and ward committeepersons in the county (10 ILCS 5/7-8(d)).

Do all committeepersons have equal votes? No. A precinct committeeperson has one vote for each ballot cast in the precinct by the party's primary voters at the primary where they were elected. Ward and township committeepersons vote by the ballots in their ward or township at the preceding General Assembly primary.

Does the county chair pick election judges? The county board appoints them, from lists certified by the county chairs of the two leading parties. The chairs are to list people who live in the precinct where possible (10 ILCS 5/13-1).

How are state central committee members chosen? By the method the Election Code and your party's rules set. Ask your county chair or read the statute on ilga.gov; we do not summarize it here.

Does Cook County work the same way? The weighted county committee is the same idea, but Cook elects ward and township committeepersons every four years instead of precinct committeepersons every two.
