Map showing Cook County subcircuit boundaries

Many Cook County voters, particularly those who have not previously voted in judicial primaries, may be uncertain about the subcircuit in which they live. Voters will find their subcircuit number on their voter's registration cards and there are a number of places on line (including on Cook County Clerk David Orr's website) where a voter can verify this information by supplying a home address.
