2006 was a midterm election year in the United States. The primaries and general elections for Cook County races coincided with those for congressional and those for state elections.
Voter turnout in Cook County during the primaries was 28.44%, with 762,273 ballots cast. The city of Chicago saw 32.05% turnout and suburban Cook County saw 26.70% turnout.[4][5]
The general election saw 49.85% turnout, with 1,350,918 ballots cast. The city of Chicago saw 49.25% turnout and suburban Cook County saw 50.45% turnout.[1][6][7]
In the 2006 Cook County Assessor election, incumbent Assessor James Houlihan, a Democrat first appointed in 1997 who was reelected in 1998 and 2002, was again reelected.[9]
In the 2006 President of the Cook County Board of Commissioners election, incumbent President Todd Stroger, a Democrat appointed following the resignation of his father John Stroger, was elected to a full term. Originally, then-incumbent John Stroger had been running for reelection, winning the Democratic primary, before backing-out and also resigning from the presidency.
Suffering health ailments, John Stroger was removed from the ticket in June and replaced by his son Todd Stroger.[11] John Stroger retired in August, and Bobbie L. Steele was appointed to fill out the remainder of his unexpired term.[12]
President of the Cook County Board of Commissioners election[1]
Fifteen members were reelected. One incumbent Democrat withdrew from their election after being renominated, while one incumbent Republican lost his primary. No seat changed parties.[2][3][1]
In the 2006 Cook County Board of Review election, two seats, one Democratic-held and one Republican-held, out of its three seats were up for election.
The Cook County Board of Review has its three seats rotate the length of terms. In a staggered fashion (in which no two seats have coinciding two-year terms), the seats rotate between two consecutive four-year terms and a two-year term.[13]
Incumbent second-term member Maureen Murphy, a Republican last reelected in 2002, lost reelection to Democrat Brendan F. Houlihan. This election was to a four-year term.[13]
No candidates, ballot-certified or formal write-in, ran in the Democratic primary.[2][3] Incumbent Republican Maureen Murphy successfully challenged the nomination petitions of the only Democrat running, Brendan Houlihan, meaning that he was removed from the Democratic primary ballot. However, since, consequentially no candidate appeared on the ballot in the Democratic primary, state law enabled the Democratic committeemen from the Board of Review's 1st district to pick a nominee. They ultimately selected Houlihan as their nominee.[14]
Incumbent second-term member Joseph Berrios, a Democrat last reelected in 2002, was reelected. Berrios had not only served since the Board of Review was constituted in 1998, but had also served on its predecessor organization, the Cook County Board of (Tax) Appeals, for ten years. This election was to a two-year term.[13]
In the 2006 Metropolitan Water Reclamation District of Greater Chicago election, three of the nine seats on the Metropolitan Water Reclamation District of Greater Chicago board were up for election in an at-large race.[2][3] Since three six-year seats were up for election, voters could vote for up to three candidates and the top-three finishers would win.
Incumbent commissioner, Democrat Terrence J. O'Brien, was reelected.[15] Winners also included newly-elected Democrats Debra Shore and Patricia Horton.[16][17] The two incumbents who did not seek reelection were James Harris and Harry Yourell.[18]
