The Democratic Party of Cook County

The Cook County Democratic Party has been known colloquially at times as the Democratic Organization, the Regular Democratic Organization, the Regular Democratic Party, and other variants. Some local ward and township committees still officially use those terms. By any name, the party proudly endorses and supports all Democratic candidates whether at the federal, state or local level. These candidates deserve our support, as they offer the best vision and policies for a brighter, more prosperous future for all.

During this critical time that will affect generations to come, the Cook County Democratic Party will represent and protect the interests of working people and guarantee personal liberties for everyone.

Our headquarters is located at 134 N. LaSalle St., Chicago, IL, 60602. To contact us, call (312) 263-0575 or email
