"We have a historic opportunity in this cycle. And that results from a billion dollar investment from the federal government in our residents and local government. And we're going to be investing in increasing our footprint in behavioral health, a guaranteed income pilot, which will be the nation's largest, and trying to help our residents with medical debt. Those are the three big, innovative initiatives we'll undertake, but we'll also do the kind of infrastructure improvements and investments in social services that we have done historically in Cook County," Preckwinkle said, when asked about her priorities if reelected.

Richard Boykin is a practicing attorney. His political experience includes serving as chief of staff to Congressman Danny Davis. And from 2014 to 2018, he served as Cook County commissioner. He said the area is facing a public safety crisis.
"I'm running for board president because gun violence, carjacking, retail thefts, all of these things have combined to terrorize communities. Our children are literally dying in the streets; families are not getting justice. My No. 1 priority is to make sure that we have safe streets throughout Cook County," he said.

The third Democratic candidate for Cook County Board president is Zerlina Smith-Members. She's a South Austin resident and activist who has said she was inspired by her grandmother. In 2019, she ran for Chicago City Council to represent the 29th ward. She said her top priority if elected would be "to make sure that we put the dignity and respect back into the county environment. We at this moment know the county is understaffed, we know the county has an $8.1 billion budget, but yet it still doesn't provide the adequate services that the residents or the employees of the county deserve and need, so make sure we put the people first. That would be my main priority."
