Candidate statement: "I believe that the State’s Attorney of Cook County plays two important roles. The first is to prosecute crime no matter who commits it. That means being tough on crime without regard to race, uniform, politics or money. The job requires a dogged determination to remain wide-eyed about evidence … and blind to outside influence."

Candidate statement: "I have devoted my entire legal career to public service as an Assistant State’s Attorney, working for justice, fairness and compassion and advocating for victims of crime across Cook County."

Candidate statement: "I am running for State’s Attorney because our criminal justice system is broken–and incumbent State’s Attorney Anita Alvarez is part of the problem."

Candidate statement: "I ask you for your vote, because, in these very serious times, especially for our criminal justice system, it's important that we have a Clerk of Court, that will protect court records for all the people, not just for the privileged few."

Candidate statement: "My vision for the Metropolitan Water Reclamation District is to provide the Chicagoland area with a strong infrastructure system that will last the next 100 years."

Candidate's vision for this office: "As commissioner, I have worked to ensure homeowners and property owners receive a full and fair review of the assessed values of their property so they pay only their fair share in property taxes, while also guaranteeing schools and local communities receive these tax proceeds on time."

Candidate statement: "My guiding vision for the Cook County Recorder of Deeds is 'Accuracy-Efficiency-Advocacy.' That means protecting an accurate public record of property ownership and doing it with only the minimum amount of taxpayer resources needed to get the job done."
