Democrats maintained their supermajority in the Illinois State Senate in the 2018 elections, controlling 40 seats to Republicans' 19. As of 2018, a party needed to control 36 seats in the Senate to have a three-fifths supermajority.
A total of 39 seats out of the chamber's 59 seats were up for election in 2018. Heading into the election, Democrats controlled 37 seats and Republicans controlled 22.
Democrats gained a trifecta in Illinois in 2018 by holding the state House and the state Senate and winning the governor's office.
Under the Illinois Constitution of 1970, senators are divided into three groups, each group having a two-year term at a different part of the decade between censuses, with the rest of the decade being taken up by two four-year terms. Depending on the election year, roughly ⅓, ⅔, or all of the Senate seats may have terms ending.[1]
The Illinois State Senate was one of 87 state legislative chambers with elections in 2018. There are 99 chambers throughout the country. In 2017, three chambers in Virginia and New Jersey were up for election. In 2016, 86 out of 99 legislative chambers held elections. Prior to 2018, the Illinois State Senate last held elections in 2016.

The Democratic Party attained supermajority status in both chambers of the Illinois General Assembly in the 2018 election. Democrats in the Illinois State Senate already held a supermajority, but Democrats in the Illinois House of Representatives did not previously hold the minimum 71 seats needed for a supermajority. In the state Senate, 39 out of 59 seats were up for election. Democrats increased their supermajority in the Illinois State Senate from 37-22 to 40-19.

Process to become a candidate
See statutes: Chapter 10, Section 5, Article 7 of the Illinois Statutes
In Illinois, a candidate may run with an established political party, with a new party, as an independent candidate, or as a write-in candidate. Candidate qualification processes are detailed below.[5]
Political party candidates and independent candidates
Established political party candidates, new party candidates, and independent candidates must file nomination papers with the Illinois State Board of Elections in order to qualify for placement on the ballot. These nomination papers must be filed during the designated filing period. The filing period for established party candidates begins 113 days before the primary election and ends 106 days before the primary election. New party and independent candidates have a separate filing period. Their filing period begins 141 days before the general election and ends 134 days before the general election.[6][5]
Nomination papers include the following:[5]
- The statement of candidacy must indicate the candidate's address, the office being sought, and the candidate's political party designation (if applicable). This form also includes a statement affirming that the candidate is qualified for the office being sought. This form must be signed by the candidate and notarized.[7]
- The original statement of economic interests must be filed with the Illinois Secretary of State, which will then issue the receipt of the statement of economic interests for the candidate to file with the Illinois State Board of Elections. This form is not required from candidates seeking federal office. It is suggested that this form be filed at the same time as all other nomination papers, but it may be filed after the other papers as long as it is filed within the candidate filing period.[5]
- The loyalty oath form is optional. If a candidate chooses to sign it, he or she must affirm that he or she is not affiliated directly or indirectly with any organization that seeks to overthrow the government of the United States or the state of Illinois.[5][8]
- A petition containing the signatures of qualified electors. A candidate can begin circulating petitions 90 days before the last day of the filing period. Signature requirements for petitions vary according to the candidate's political party affiliation and the office being sought. Signature requirements are detailed in the table below.[5][9][10]
| Petition signature requirements | |||
|---|---|---|---|
| Office | Established party candidates | New party candidates | Independent candidates |
| Statewide office (e.g., governor and lieutenant governor, attorney general, secretary of state, comptroller, treasurer) | 5,000 (no more than 10,000) primary voters belonging to the candidate's party | 1% of the number of voters who voted in the most recent general election or 25,000, whichever is less | 1% of the number of voters who voted in the most recent general election or 25,000, whichever is less |
| United States Representative | 0.5% of primary voters in the district belonging to the candidate's party | 5% of the total number of district voters who voted in the last general election | 5% of the total number of district voters who voted in the last general election |
| State senator | 1,000 (no more than 3,000) district voters belonging to the candidate's party | 5% of the total number of district voters who voted in the last general election | 5% of the total number of district voters who voted in the last general election |
| State representative | 500 (no more than 1,500) district voters belonging to the candidate's party | 5% of the total number of district voters who voted in the last general election | 5% of the total number of district voters who voted in the last general election |
Any objections to nomination papers must be filed no later than five business days after the filing deadline.[11]
Write-in candidates
Write-in votes will not be counted unless the candidate files a declaration of intent no later than 61 days before the election in which he or she is running. This form must indicate the office being sought by the candidate.[5][12]
Qualifications
Article IV of the Illinois Constitution states: To be eligible to serve as a member of the General Assembly, a person must be a United States citizen, at least 21 years old, and for the two years preceding his election or appointment a resident of the district which he is to represent.

Trifectas
A state government trifecta is a term that describes single-party government, when one political party holds the governor's office and has majorities in both chambers of the legislature in a state government. Illinois came under divided government following the 2014 elections when Republicans won control of the governor's office and Democrats retained control of the state legislature. Prior to the 2014 elections, Democrats had held a trifecta since the 2002 elections. From 1992 to 2017, there were 12 years of Democratic trifectas and two years of Republican trifectas.

Political context of the 2018 elections
Key issues
2017 budget conflict
- See also: State budget conflicts, 2017
- In 2017, disagreements between Governor Bruce Rauner (R) and the Democratic-controlled Illinois General Assembly over the state budget drew national attention when S&P Global Inc. and Moody’s Investors Service downgraded Illinois' credit rating and some government services, including transportation projects and the state lottery, were on the verge of being shut down.[15][16] Rauner and the legislature failed to come to an agreement on a budget during the regular session, which ended on May 31, leading Rauner to call a special session from June 21 to June 30, the last day of the 2017 fiscal year. A budget agreement was not reached before June 30, meaning Illinois entered the 2018 fiscal year without a budget.
- A budget was passed on July 6, 2017, when the legislature overrode Rauner's vetoes of a $36 billion spending plan and a $5 billion tax increase. In the votes in the Illinois House, 10 Republicans joined the Democrats in voting for the overrides. Up to this point, Illinois had not passed a budget since 2014, when Pat Quinn (D) served as governor. According to The Associated Press, two years was the longest any state had gone without a budget in recent memory.[17]
- Important issues surrounding the budget debate included differences in Democratic and Republican plans concerning income tax rate increases, a property tax freeze, changes to regulations related to injured worker compensation, and the state's pension liabilities. The budget deal that eventually passed increased the personal income tax rate from 3.75 to 4.95 percent, increased the corporate tax rate from 5.25 to 7 percent, and left overall spending at $36 billion for fiscal year 2018.[18]
- The budget had an impact beyond the state, costing Wisconsin millions from its state budget. This was because, as of July 2017, Illinois and Wisconsin had a reciprocity agreement to account for the greater number of Wisconsinites that cross the state border to work in Illinois, but not pay state income taxes, than Illinoisans who came to work in Wisconsin. With higher incomes taxes in Illinois, Wisconsin's reciprocity payment increased.[19]
- Coverage of the budget negotiations centered on the relationship between Rauner and Speaker of the House Michael Madigan (D).[20] As of July 6, 2017, Rauner was seeking re-election as governor in 2018 and Madigan was defending the Democrats' 67-51 majority in the state house. Rauner and Madigan disagreed on a number of issues including whether the income tax increases should have been permanent.[21]
Education funding
- $8.2 billion in state aid for public schools was included in the budget agreement. However, language was also included that said $6.76 billion of the aid had to be dispersed through a funding formula that calculated state aid for school districts based on the cost of strategies that supporters say are proven to improve student performance. The funding for districts could be increased by elements such as income, property wealth, and English-learning needs.[22][23][24] On August 29, the Illinois General Assembly passed a bill that included the necessary funding formula. Read more the timeline of events below.
- On May 31, the Legislature passed SB 1, which contained the necessary funding formula. Gov. Rauner indicated that he would veto the bill, causing Senate President John Cullerton (D) to hold it in the chamber.[25] According to Rauner's office, the governor would not support the bill because he believed it would benefit Chicago at the expense of other areas of the state.[26]
- On July 24, Rauner called the General Assembly into a special session starting July 26 to address education funding. He had set a deadline of 12:00pm CT on July 24 for Cullerton to send him SB 1 so that he could use his amendatory veto power to make unspecified changes to the provisions he disagreed with. When the deadline passed without Cullerton sending him the bill, he called the special session.[27] On July 31, the last day of the special session, SB 1 was transmitted to Rauner.[28]
- Rauner issued an amendatory veto on August 1, rewriting SB 1 to remove a $250 million block grant to Chicago Public Schools and changing how the funding formula determines state aid.[29] According to the Illinois State Board of Education, Rauner's changes would result in a $463 million decrease in funding for Chicago Public Schools in the 2017-2018 school year.[30] The Illinois Senate met on August 13 and overrode the veto by a 38-19 vote, with all Democrats and Republican Sam McCann voting to override.[31] The Illinois House was scheduled to vote on the override on August 23, but Speaker Madigan cancelled the vote on August 22. He said that progress had been made in negotiations with Rauner and Republicans.[32][33][34]
- On August 24, the four leaders in the General Assembly— Madigan, Cullerton, Senate Minority Leader Bill Brady (R), and House Minority Leader Jim Durkin (R)— announced that they had reached a compromise agreement on SB 1. According to Politico, the agreement kept the funding formula from SB 1 and included $75 million in subsidies for private school education.[35] On August 28, 2017, the Illinois House rejected the agreement in a 46-61 vote.[36] The chamber next voted on an override of SB 1. After the override vote received just 63 of the 71 votes it needed to pass, the chamber took up the compromise bill again and passed it 73-34.[37] On August 29, the Illinois Senate passed the compromise bill by a 38-13 vote.[38] Gov. Rauner signed the bill into law on August 31.[39]
- According to The Chicago Sun-Times, some schools in low-income areas cannot remain open without the state money that is allocated by the budget.[22] In addition to the state aid in the budget, education funding in Illinois also comes from property taxes levied by local governments. Areas that pay more in property taxes can spend more on schools and are less dependent on state aid.[40]
Rauner signs HB 40
On September 28, 2017, sitting Gov. Bruce Rauner (R) signed HB 40, a bill passed by the state Legislature that spring. The bill removed a provision in Illinois law that would have made abortion illegal in the state in the event that the U.S. Supreme Court overturned its ruling in Roe v. Wade. The bill also required that Medicaid and state employee health insurance plans cover abortions.[41] Rauner's decision to sign the bill was criticized by opponents of the bill within the Illinois Republican Party, who argued that the governor had indicated in the spring that he would issue a veto if given the opportunity. A Chicago Tribune story published shortly after Rauner's signature reported that State House Minority Leader Peter Breen (R) had called for members of the Illinois Republican Party to unite behind a candidate to challenge Rauner.[42] At the time of Rauner's signature on HB 40, he had one declared opponent in the Republican primary, William Kelly.
This chart tracks Illinois Republican state legislators that Ballotpedia identified as opposing Gov. Rauner's signing of HB 40. Their positions were determined by their public statements. As of October 10, 2017, four of 22 Senate Republicans—18.2 percent—had publicly opposed Rauner on HB 40.

Wave election analysis
- See also: Wave elections (1918-2016)
The term wave election is frequently used to describe an election cycle in which one party makes significant electoral gains. How many seats would Republicans have had to lose for the 2018 midterm election to be considered a wave election?
Ballotpedia examined the results of the 50 election cycles that occurred between 1918 and 2016—spanning from President Woodrow Wilson's (D) second midterm in 1918 to Donald Trump's (R) first presidential election in 2016. We define wave elections as the 20 percent of elections in that period resulting in the greatest seat swings against the president's party.
Applying this definition to state legislative elections, we found that Republicans needed to lose 494 seats for 2018 to qualify as a wave election.
The chart below shows the number of seats the president's party lost in the 10 state legislative waves from 1918 to 2016. Click here to read the full report.

Competitiveness
Every year, Ballotpedia uses official candidate lists from each state to examine the competitiveness of every state legislative race in the country. Nationally, there has been a steady decline in electoral competitiveness since 2010. Most notable is that the number of districts with general election competition has dropped by more than 10 percent.

Historical context
Uncontested elections: In 2014, 32.8 percent of Americans lived in states with an uncontested state senate election. Similarly, 40.4 percent of Americans lived in states with uncontested house elections. Primary elections were uncontested even more frequently, with 61 percent of people living in states with no contested primaries. Uncontested elections often occur in locations that are so politically one-sided that the result of an election would be a foregone conclusion regardless of whether it was contested or not.
Open seats: In most cases, an incumbent will run for re-election, which decreases the number of open seats available. In 2014, 83 percent of the 6,057 seats up for election saw the incumbent running for re-election. The states that impose term limits on their legislatures typically see a higher percentage of open seats in a given year because a portion of incumbents in each election are forced to leave office. Overall, the number of open seats decreased from 2012 to 2014, dropping from 21.2 percent in 2012 to 17.0 percent in 2014.
Incumbent win rates: Ballotpedia's competitiveness analysis of elections between 1972 and 2014 documented the high propensity for incumbents to win re-election in state legislative elections. In fact, since 1972, the win rate for incumbents had not dropped below 90 percent—with the exception of 1974, when 88 percent of incumbents were re-elected to their seats. Perhaps most importantly, the win rate for incumbents generally increased over time. In 2014, 96.5 percent of incumbents were able to retain their seats. Common convention holds that incumbents are able to leverage their office to maintain their seat. However, the high incumbent win rate may actually be a result of incumbents being more likely to hold seats in districts that are considered safe for their party.
Marginal primaries: Often, competitiveness is measured by examining the rate of elections that have been won by amounts that are considered marginal (5 percent or less). During the 2014 election, 90.1 percent of primary and general election races were won by margins higher than 5 percent. Interestingly, it is usually the case that only one of the two races—primary or general—will be competitive at a time. This means that if a district's general election is competitive, typically one or more of the district's primaries were won by more than 5 percent. The reverse is also true: If a district sees a competitive primary, it is unlikely that the general election for that district will be won by less than 5 percent. Primaries often see very low voter turnout in comparison to general elections. In 2014, there were only 27 million voters for state legislative primaries, but approximately 107 million voters for the state legislative general elections.
