Election information.
1986 was a midterm election year in the United States.
Creation of the Illinois Solidarity Party.
After LaRouche movement disciples won the Democratic primaries for Lieutenant Governor and Secretary of State, Adlai Stevenson III created the Solidarity Party primarily to run Democratic candidates against them in the general election. He himself dropped off of the Democratic ticket for Governor, which he had won the primary for, and ran instead as the Solidarity Party candidate for Governor. The two Lyndon LaRouche-affiliated candidates, Mark J. Fairchild for Lieutenant Governor and Janice Hart for Secretary of State, had not seen their affiliations with LaRouche well-publicized until after they won their upset primary defeats over Stevenson-backed candidates George Sangmeister and Aurelia Pucinski. 
Illinois law required any unestablished party to run a full slate in order to obtain ballot access, thus, Stevenson ran candidates in all races.
Turnout.
Turnout in the primary was 26.23%, with 1,602,156 ballots cast. 1,014,908 Democratic and 570,661 Republican primary ballots were cast.
Turnout in the general election was 55.34%, with 3,332,450 ballots cast.

State elections.
Governor and Lieutenant Governor.
Incumbent Governor James R. Thompson won reelection to a fourth term, defeating Adlai Stevenson III. This was a rematch of the previous 1982 gubernatorial election, which saw Stevenson as a Democratic nominee.
Stevenson, who had won the Democratic gubernatorial primary, withdrew from the Democratic ticket after Mark Fairchild, a follower of Lyndon LaRouche, won the Democratic primary for lieutenant governor. Stevenson refused to run on a ticket with supporters of LaRouche's ideology. Stevenson instead created the Illinois Solidarity Party and ran as its nominee.
Attorney General.
Incumbent Attorney General Neil Hartigan, a Democrat, was reelected to a second term.
Democratic primary.
Incumbent Neil Hartigan defeated Chicago alderman Martin J. Oberman in the Democratic primary.
Hartigan had originally declared his intention to forgo seeking reelection, and instead run for governor, but he ultimately reversed course and sought reelection after Adlai Stevenson III entered the race for governor.
Republican primary.
Republican Village President of Arlington Heights James T. Ryan won the Republican primary, running unopposed. Ryan stepped-down as nominee after allegations arose that he had committed domestic abuse against both his wife and ex-wife, which arose soon after he received his party's nomination.
There had been originally been several other candidates running for the Republican nomination in the primary, but all withdrew soon after Democratic incumbent Hartigan announced that he would seek reelection.
If he had been elected, Ryan would have been the first Republican sitting mayor elected to statewide office in Illinois since Edward C. Akin was elected Attorney General in 1898.
After Ryan withdrew as the Republican nominee, he was replaced on the ballot by Bernard Carey, a member of the Cook County Board of Commissioners who had also formerly served as Cook County State's Attorney from 1972 through 1980. Ryan's withdrawal had taken place five months before the general election.
Secretary of State.
Incumbent Secretary of State Jim Edgar, a Republican first appointed in 1981 and subsequently elected to a full term in 1982, was reelected to a second full term.
Democratic primary.
Little known candidate Janice Hart won an upset victory over Aurelia Pucinski (who had the backing of Adlai Stevenson III and others). While, not well-reported until "after" the primary, Hart was a member of the LaRouche movement.

Democratic primary.
Incumbent James Donnewald lost renomination to former Treasurer Jerome Cosentino. Donnewald had been the party organization's favored candidate. Other candidates running included Cook County Board of Appeals member Pat Quinn and LaRouche movement member Robert D. Hart (who had the formal backing of Lyndon LaRouche's NDPC).
Republican primary.
J. Michael Houston, the mayor of Springfield, won the Republican nomination. Houston was seeking to become the first Republican Illinois Treasurer in over twenty years.
