Regularly-scheduled election

Three six-year term seats were up for the regularly-scheduled election. Since three six-year seats were up for election, voters could vote for up to three candidates, and the top-three finishers would win.

Two of the incumbents for the three seats were seeking reelection, Barbara McGowan and Mariyana Spyropoulos, both Democrats.^[13] Each won reelection. The third, newly elected, winner of the general election was fellow Democrat Josina Morita.

Unexpired term (2 years)

A special election was held to fill the seat vacated when Patrick Daley Thompson resigned to assume office as a Chicago alderman.^[14] This seat had been filled with an interim appointment by Governor Bruce Rauner of David J. Walsh.^[15] Walsh was a Republican.^[16]

Clerk-Recorder Office

A ballot question was referred by the Cook County Board of Commissioners to the voters of Cook County as to whether the position of Cook County Recorder of Deeds should be eliminated, and its duties merged into the position Cook County Clerk. Voters ultimately approved the ballot question.

The sponsor of the legislation passed by the Cook County Board of Commissioners which created the ballot question was John Fritchey.^[18] The legislation to create this ballot question passed unanimously in a vote of all seventeen members of the Board of Commissioners.^[18]

The last time the county had voted by referendum on whether to eliminate an elected office was in 1972, when voters strongly voted in favor of eliminating the elected position of Cook County Coroner, replacing it with an appointed medical examiner.^[19]

The ballot measure asked the question,

Shall the Office of the Cook County Recorder of Deeds be eliminated and all duties and responsibilities of the Office of the Cook County Recorder of Deeds be transferred to, and assumed by, the Office of the Cook County Clerk by December 7, 2020?^[20]

Earned Sick Time

A ballot question was created by a successful citizen initiative petition which asked Cook County voters whether they believed that Illinois should enact the Earned Sick Time for Employees Act, thus allowing Illinois workers to earn up to 40 hours of paid sick leave.^[21]

The ballot measure asked the question,

Shall Illinois enact the Earned Sick Time for Employees Act which will allow Illinois workers to earn up to 40 hours of sick time a year to take care of their own health or a family member's health?^[21]
