The Cook County Democratic Party is an American county-level political party organization which represents voters in 50 wards in the city of Chicago and 30 suburban townships of Cook County. The organization has dominated Chicago politics (and consequently, Illinois politics) since the 1930s. It relies on an organizational structure of a ward or township committeeperson (until 2018 legal name change, "committeeman") to elect candidates. At the height of its influence under Richard J. Daley in the 1960s, in contrast to other American big city political machines which saw decline in political patronage in employment in the wake of the New Deal reforms of the 1930s, it was one of the most powerful political machines in American history. By the 1980s, the party had largely ceased to function as a machine due to the legal dismantling of the patronage system under the Shakman Decrees issued by the federal court in Chicago. The current Chair is Toni Preckwinkle, who is also the elected Cook County Board president.

Organization and leadership Article I of the by-laws of the Cook County Democratic Party states that the party exists to "attract, endorse, and support qualified Democratic candidates for office, to develop positions on issues of public importance, to advance the ideals and principles of the Democratic Party, and to seek to improve the lives of the people of Cook County through effective, efficient, and fair government." The by-laws also state that the party must "promote Democratic political activity in Cook County and encourage broad and diverse political participation by Cook County Democrats regardless of race, color, creed, national origin, gender, physical ability or sexual orientation ... and take an active role in county, state, and national political efforts which have an impact upon the people of Cook County."By-laws of the Cook County Democratic Party: Article I: Organization and Purpose p. 1

The party was chaired by 31st ward committeeman Joseph Berrios from 2007 until April 2018, when Cook County President Toni Preckwinkle replaced him.Chicago Tribune: Democrats elect a new chief The Executive Committee has eight other officers: two Executive Vice-Chairs, First Vice-Chair, City Vice-Chair, Suburban Vice-Chair, Secretary, Treasurer, and Sergeant-At-Arms. Each of the 50 wards of Chicago and the 30 suburban townships has its own committee and is represented in the Central Committee by an elected committeeperson (until 2018 legal name change, "committeeman").

In suburban Cook County, regional groups, such as the Southland Democrats, co-ordinate activities with their local Democratic township organizations and their committeemen.Southland Democrats: Democratic Organizations Article IV, Section 4 of the By-laws of the Cook County Democratic Party allows the Suburban Vice-Chair (a position currently held by Illinois State Senator Don Harmon) the authority to "convene caucuses and meetings, solicit support for the organization, assist the County Chair in any matters upon request, coordinate activities concerning recommendations for endorsements of candidate, and bring before the Central Committee issues of particular interest."By-laws of the Cook County Democratic Party: Article IV: Officers, Powers and Duties p. 4

History

Early history Cook County was created on 15 January 1831 and it was named after Daniel Cook. Cook had been one of the earliest and youngest statesmen in Illinois history and he was a registered Democrat in Randolph County. By 1837, local Democrats were winning electoral victories under the leadership of William B. Ogden. Ogden recruited Irish immigrants into the party. Their loyalty to native Democrats was established in return for petty political favors and an occasional elected office.Holli, Melvin G. and Petre d'A. Jones, editors; "Ethnic Chicago" (1995) p. 414 The careers of Irish Democrats from this period, such as John Comiskey from the Blue Island area, were still limited by anti-Irish discrimination.Holli, Melvin G. and Petre d'A. Jones, editors; "Ethnic Chicago" (1995) p. 416 Prior to the American Civil War, the city of Chicago and Cook County had created a strong two-party tradition.Encyclopedia of Chicago: Machine Politics The local Democratic Party grew stronger in the decades that followed the Great Chicago Fire due in part to an influx of new immigrants from eastern and southern Europe.Holli, Melvin G. and Petre d'A. Jones, editors; "Ethnic Chicago" (1995) p. 417 By 1890, Roger Charles Sullivan had accumulated major influence within the tumultuous Cook County Democratic Party. He would come to dominate the organization for two decades and he was a national figure during the age when urban political bosses reached the height of their power and prestige. After his death, he was followed as chairman by George Brennan in 1920.Holli, Melvin G. and Petre d'A. Jones, editors; "Ethnic Chicago" (1995) p. 433

Prior to the death of party chairman George Brennan in 1928,Holli, Melvin G. and Petre d'A. Jones, editors; "Ethnic Chicago" (1995) p. 444 the Democratic Party in Cook County was divided along ethnic lines – the Irish, Polish, Italian, and other groups each controlled politics in their neighborhoods and municipalities. Under the leadership of Anton Cermak, a Czech American, the party combined its ethnic bases into one large organization. With the organization behind him, Cermak was able to win election as mayor of Chicago in 1931, an office he held until his assassination in 1933.O'Connor, Len; "Clout: Mayor Daley and His City". (1975) pp. 37-39Holli, Melvin G. and Petre d'A. Jones, editors; "Ethnic Chicago" (1995) p. 451 After Cermak's death, Patrick Nash and Edward J. Kelly consolidated the Cook County Democratic Party into a political machine.O'Connor, Len; "Clout: Mayor Daley and His City". (1975) p. 45Holli, Melvin G. and Petre d'A. Jones, editors; "Ethnic Chicago" (1995) p. 437

Nash and Kelly were able to bring African-Americans, who had been predominantly Republicans since the Civil War, into the Democratic Party. Nash died in 1943 and Kelly took over as Chairman of the Cook County Democratic Party. The extensive corruption that took place during Kelly's tenure caused him to become unelectable.O'Connor, Len; "Clout: Mayor Daley and His City". (1975) pp. 54-55 Jacob Arvey assumed the position of Chairman of the organization after Kelly's ouster in 1947.O'Connor, Len; "Clout: Mayor Daley and His City". (1975) p. 56Holli, Melvin G. and Petre d'A. Jones, editors; "Ethnic Chicago" (1995) p. 457 Arvey put reformers on the slate, such as Martin H. Kennelly for mayor, Paul Douglas for United States Senate, and Adlai Stevenson for governor of Illinois.O'Connor, Len; "Clout: Mayor Daley and His City". (1975) pp. 60-61 During the early years of the 1950s, Joseph L. Gill – George Brennan's brother-in-law – replaced Arvey as Chairman of the party. His role was more of a caretaker than that of a political leader.

Under Richard J. Daley The Democratic committeemen of Cook County elected Richard J. Daley as their chairman in 1953 and the Democratic committeemen of Chicago slated him as their mayoral candidate in 1955. He served as chairman for 22 years and as mayor for twenty years.O'Connor, Len; "Clout: Mayor Daley and His City". (1975) pp. 11, 12O'Connor, Len; "Clout: Mayor Daley and His City". (1975) p. 121 This was accomplished with the help and support of William L. Dawson. In return, an African-American "sub-machine" led by Dawson was created under the umbrella of the regular machine. In the predominantly African-American wards, Dawson was able to act as his own political boss. He amassed a considerable power base by awarding political appointments to his allies,Dawson, William Levi, (1886–1970) just as Daley did in the larger machine. However, Dawson's machine had to continually support the regular machine in order to retain its own clout.O'Connor, Len; "Clout: Mayor Daley and His City". (1975) pp. 110, 113

Daley helped turn out the vote for John F. Kennedy in the 1960 presidential election. Kennedy won Illinois by 9,000 votes, yet won Cook County by 450,000 votes, with some Chicago precincts going to Kennedy by over 10 to 1 margins. Illinois' 27 electoral votes helped give Kennedy the majority he needed.O'Connor, Len; "Clout: Mayor Daley and His City". (1975) pp. 158-162 Chicago was selected to host the 1968 Democratic National Convention. Political commentator Len O'Connor described this period as Richard J. Daley's "High Water Mark" and described the Cook County Democratic Party at the time as one of the most powerful political machines in American history.

Under George Dunne and Edward Vrdolyak The Shakman Decrees introduced judicial oversight of City and County hiring, reducing the number of voters who owed their livelihoods to the Democratic party.Cook County Shakman Compliance Administrator: Background The 1968 convention had ended in disaster. The Walker Report concluded that a "police riot" had taken place at the 1968 Democratic National Convention in Chicago.Federal Judicial Center: The Chicago Seven Conspiracy Trial NBC News had televised the event and switched back and forth between demonstrators being beaten by the police in front of the convention hall and the festivities over Humphrey's victory inside.NBC Morning News, August 29, 1968. Racial tension over issues such as urban renewal in Woodlawn and Lincoln Park, red lining, open housing and public school desegregation alienated African-Americans and Latinos voters. Though Daley himself never faced any criminal charges, a number of his associates did, including Thomas Keane and Arvey. After Daley's death in 1976, no mayor has served as chairman of the Cook County Democratic Party.Oxford Dictionary of Political Biography: Jane Byrne Michael Bilandic, Daley's successor as mayor, lost in a 1979 mayoral primary to Jane Byrne.Chicago Tribune: Jane Byrne elected mayor of Chicago In Bilandic's obituary, The New York Times wrote that the operation of the Cook County Democratic Party as a political machine ended during Bilandic's mayoralty.New York Times: Michael Bilandic, Daley Successor in Chicago, Dies at 78

Byrne's base of support was on the Northwest side of Chicago, and to a lesser extent the Southeast and Southwest, and she also benefited from independent African-American electoral support.WBEZ: This American Life 84: Harold Originally a Richard J. Daley appointee, Byrne did not have the backing of the influential ward committeemen such as John Daley, Michael Madigan, or Thomas Hynes. For a short while after Byrne's election Richard J. Daley's successor as Democratic County Party Chairman George Dunne supported her.Illinois Issues #18: After Byrne's Win In 1979, Oak Park Democratic committeeman and State Senator since 1970, Philip J. Rock became the Illinois State Senate's top Democrat. He would serve as such for the next 14 years and he would retire as the longest serving President of the Senate and Majority Leader in state history.Illinois Department of Central Management Services: Rock, Phil
