CHICAGO (AP) — A group hoping to change the way Illinois draws its political boundaries is acknowledging flaws in its failed campaign while pledging to make another attempt in the next several years.

Deborah Harrington is head of Yes for Independent Maps. She says the group will put lessons learned in the campaign to good use.

Cook County Circuit Court Judge Mary Mikva ruled Friday that the redistricting measure and another calling for term limits didn’t meet constitutional requirements for getting on the November ballot.

The Illinois State Board of Elections also questioned the number of valid signatures the redistricting group had collected.

Lawyers involved with the effort considered an appeal but decided a fresh attempt stood a better chance.

Harrington says redistricting reform efforts in other states, including California, took several tries.
