Lisle 2026 Voter Guide: Everything You Need To Know

LISLE, IL — The General Election is less than a month away on Nov. 3, and will include the gubernatorial race, as well as various county races including for DuPage County Sheriff and County Board positions. Lisle voters will also see a question from the Lisle Park District about a $29.5 million bond referendum to help fund a new indoor recreation center.

Here's everything you need to know to cast your vote, from voter registration to polling places to mail-in voting to what's on the ballot.

Lisle Park District Bond Referendum

The ballot for Lisle voters will include a question for the Lisle Park District's proposed $29.5 million bond referendum to support the construction of an indoor recreation center.

Here's how the question will appear on the ballot:

Shall the Lisle Park District, DuPage County, Illinois, replace the existing Community Center by building and equipping a new Community Activity Center with a fitness area with cardio and strength equipment, an indoor walking/jogging track, multi-court gymnasiums, and flexible programming spaces and issue its bonds to the amount of $29,750,000 for the purpose of paying the costs thereof?

Congressional Races

There are two races to watch for Downers Grove residents:

• 6th Congressional District: Conforti, Casten, Set For Rematch
• 11th Congressional District: Incumbent Democrat Bill Foster faces Republican nominee Jeff Walter

DuPage County Sheriff

No matter how they vote, DuPage County residents will get a new sheriff. Democrat Peter Coolidge is facing off against Republican Sean Noonan. They are vying to succeed Republican James Mendrick, who decided against seeking a third term, instead unsuccessfully running for the Republican gubernatorial nomination.

The general election race for sheriff is quieter than the one in the Republican primary. That is when candidate Eddie Moore, the undersheriff, faced controversies such as his handling of a car crash and a bar incident from years before. Noonan defeated him.

DuPage County Government Contested Races

Several DuPage County offices will have contested races come Election Day.

Incumbent County Board President Deb Conroy (D) faces off against Gary Grasso (R). Conroy was elected to her four-year term in 2026.

County Clerk Jean Kaczmarek is defending her seat against Paula Deacon Garcia. Incumbent DuPage County Treasurer Gwen Henry faces off against Yeena Yoo.

DuPage County Judges Up For Retention, 1 Contested Race

Two DuPage County judges are up for retention in the 18th Judicial Circuit.
