In the 12th subcircuit, which covers some of north suburban Cook County, five candidates are vying for one judicial seat. Once elected, there is no difference in responsibility of the countywide judges and subcircuit judges. All voters will have the chance to vote for all countywide candidates, but voters only vote for subcircuit candidates in their own area. Not sure if you live in the 12th subcircuit?
