In the race for Cook County Circuit Court clerk, three candidates are vying to become the next head of the massive office that serves as the records manager for one of the largest court systems in the nation. The winner will succeed outgoing Clerk Iris Martinez, who lost in the Democratic primary in March to Mariyana Spyropoulos.

She faces Chicago police Officer Lupe Aguirre, a Republican, and Libertarian Michael Murphy.
