Bill Summary · SB 1660

Summary — SB 1660 (Elections: precinct sizing and redistricting timing)

Note: Multiple jurisdictions used the bill number “SB 1660” in 2025 for unrelated measures (e.g., Arizona, Florida, Hawaii). This summary focuses on the Illinois measure titled in the text “ELEC CD‑VOTERS PER PRECINCT” (introduced by Sen. Julie A. Morrison).

Purpose / Intent

The bill revises how counties set and adjust election precinct boundaries and precinct sizes. It shifts the sizing metric from “registered voters” to actual in‑person voters at the most recent general election and updates the timing and population targets used when reestablishing precinct boundaries following redistricting and the decennial census.

Key provisions

  • Precinct size metric: Requires each county board (except very large counties) to divide precincts so that, as nearly as practicable, each precinct contains 1,200 registered voters who cast a ballot in person on the day of the most recent general election — replacing or refining the prior metric based on total registered voters.
  • Large‑county thresholds: Maintains different procedures for counties with populations of 3,000,000 or more (historically treated differently); the bill also references a 1,800‑voter target in certain contexts (see redistricting rule below).
  • Post‑redistricting timing: Directs that the Board of Election Commissioners (or county board) change precinct boundaries after each decennial census as soon as practicable following the completion of congressional and legislative redistricting.
  • Single‑district requirement: Continues/clarifies requirement that each precinct be situated within a single congressional, legislative and representative district and, where applicable, not cross more than one county board district or municipal ward.
  • Conforming and technical changes: Amends related Election Code sections for consistency with the new metrics and timing.

Who is affected

  • County boards of election and county clerks (responsible for dividing precincts and selecting polling places).
  • Board of Election Commissioners in jurisdictions that use that structure.
  • Voters (potential changes to polling places and precinct assignments).
  • Local election administrators (operational, staffing, equipment planning).

Procedural status & timeline

  • Introduced: February 2025 (sponsor: Sen. Julie A. Morrison).
  • Current status (per provided file): Rule 3‑9(a) / Re‑referred to Assignments. (This indicates further committee/assignment action pending in the chamber.)
  • If enacted, counties would implement new precinct sizing and boundary changes following the next applicable redistricting/census cycle and at regular precinct‑review meetings described in statute.

Potential impacts and considerations

  • Administrative impact: Counties may need to review and redraw precincts using turnout data (in‑person votes) rather than registration counts, which could change precinct boundaries and polling places.
  • Voter convenience & wait times: Aligning precinct size with historical turnout may better match polling resources to actual demand, but practical effects will vary by county.
  • Implementation timing: Effective application depends on coordination with congressional and legislative redistricting and timing of decennial census data.

If you want, I can:
- Produce a side‑by‑side comparison of current statute vs. bill language, or
- Draft a checklist for county election officials to implement the bill’s changes.
