It appears Margaret Croke will edge out Karina Villa.
Ninety nine percent of the vote is in.
The race has not yet been called.
Villa says she won't concede until all the votes are counted.
Croke said she's confident that she will be the Democratic nominee.
She was heavily backed by Gov. JB Pritzker.
Susana Mendoza did not run for reelection.
It is a statewide office with little fanfare, but four Democratic women who wanted to become Illinois' next comptroller said it is one of the state's most important jobs, especially during a time when the Trump administration is cutting billions from Illinois.
"The comptroller's office pays the checks. And also, it's that last line of financial oversight, and all the local government audits, they go to the comptrollers. The comptroller is the person who is the last person who can raise the red flag if something if off," Illinois state Rep. Margaret Croke said.
Croke of Chicago said her experience serving in the Illinois House and working for the Department of Commerce makes her qualified.
Croke has raised more money than her opponents. Although, Illinois state Sen. Villa is a close second. Villa criticized Croke's donations because she said some came from Super Political Action Committees and Republicans.
"I'm not on the defense about where I'm getting my money. I get the money from the unions and from everyday people who want a transparent government," Villa said.
Mendoza has held the office since 2016. She is not running for reelection and backed Lake County Treasurer Holly Kim to replace her. Mendoza says after the days of former Illinois Gov. Bruce Rauner, she successfully turned Illinois' fiscal ship around, and Kim would continue in her footsteps.
"From day one to Election Day, we've been running on my experience, even the fact that on day one, I can do the job," Kim said.
But Illinois state Rep. Stephanie Kifowit said she is the candidate with the most experience. Kifowit of Oswego is a U.S. Marine veteran, a former registered financial advisor and has served 20 years in Springfield, dealing with government finance.
"I know the employees of the comptroller's office. I know the modernization act that's already in place, $53 million that individuals appreciate having somebody with knowledge and experience in such a critical role," Kifowit said.
Bryan Drew, a southern Illinois attorney, was the only Republican running for state comptroller.
