It is on the list of Illinois's parties that we assembled from state law and official candidate lists, ballots or results^1,5, because we couldn't read a single official list. A list built that way can miss a party that has status but no 2026 candidates. The state's class for it: established political party.^1,5

How a party qualifies in Illinois

A group forms a new political party by filing a petition that names the party in five words or fewer and lists its full slate of candidates for the offices to be filled at that election.^1,6 Where in the source: § 10-2 A statewide petition needs signatures from 1 percent of the voters at the last statewide general election or 25,000 voters, whichever is less; a petition for a district or local unit needs 5 percent of the voters at its last regular election, with lower fixed numbers for congressional and legislative districts in the first election after a redistricting.^1,6 Where in the source: § 10-2 Filing the petition makes the group a new political party only for placing those candidates on that one election's ballot; for 2026 the filing period was May 18 to 26, 2026.^1,6 Where in the source: § 10-2; Guide, filing periods

How a party keeps its status

A party whose candidate for governor wins more than 5 percent of the governor vote becomes, or stays, an established political party for the whole state and every district in it.^1,6 Where in the source: § 10-2 A party whose other candidates win more than 5 percent of the vote for their offices is established only where they did so, and a party whose governor candidate falls to 5 percent or less, or that runs no one for governor, stays established only in the districts where its candidates keep winning more than 5 percent.^1,6 Where in the source: § 10-2 For the 2026 elections, the State Board of Elections says the only statewide established parties are the Democratic Party and the Republican Party.¹ Where in the source: Established Political Party Candidates

Illinois's rules for nominating

Established political parties nominate their candidates for state, congressional and county offices in the primary, held March 17, 2026.^1,5 Where in the source: § 7-1(a) New political parties and independent candidates skip the primary and reach the general election ballot by petition.^1,6 Where in the source: § 10-2 A person who files in a party primary and loses, or who votes an established party's primary ballot, may not then run as a candidate of another party or as an independent in the general election that follows.^1,7 Where in the source: § 7-43

§4Notes on Illinois’s party research

What the research couldn’t find or confirm about Illinois’s parties, in its own plain words. Nothing is left out silently.

• Illinois parties can also be established, or run as new parties, in a single district, county or other local unit. We listed only parties whose candidates appear on the Board's general election lists for U.S. Senate and governor and the one district-level party we found while checking a congressional district list; we did not compile party status for every congressional, legislative, county or local race, because the Board's candidate lists for those offices are reached through search forms.
• The Board's 2026 guide confirms the established status of the Democratic and Republican parties. The classes of the American Center Party (new political party) and the Working Class Party (not recorded) rest on candidate filing dates and the guide's filing periods, not on a Board statement naming them.
• The candidate lists print party names in capital letters (AMERICAN CENTER PARTY, WORKING CLASS PARTY); we wrote them in normal capitalization. The governor list shows tickets labeled GREEN, INDEPENDENCE PARTY and NEW as Removed, so those labels are not listed as parties on the 2026 general ballot.
