Illinois results by county
The Illinois 2026 election results are not available yet: the Illinois State Board of Elections was last checked on 2026-11-13 and nothing is estimated or filled in. This page shows the saved 2022 and 2024 results by county, per the MIT Election Data and Science Lab’s precinct returns for 2022 and 2024, summed to counties and districts here (a secondary source, not checked against the state canvass). County outlines are U.S. Census Bureau cartographic boundaries (public domain).

2026 results are not available yet. Illinois’s results are posted on the State Board of Elections’ site, whose robots.txt disallows every automated reader, so we load nothing from it. Expected after a person saves the Board’s Vote Totals files or the Board provides them; the Board canvasses by December 4, 2026. We last checked the Illinois State Board of Elections on 2026-11-13. Until then this page shows past elections only, and nothing is estimated or filled in.
Read this with the numbers:
- No 2026 result is loaded. The State Board of Elections’ robots.txt disallows every automated reader, so we read nothing from its site and we call no race. We last checked on November 9, 2026.
- The 2022 and 2024 numbers are from the MIT Election Data and Science Lab, a secondary source that we have not checked against the Board’s canvass: its precinct returns, summed to counties and districts. Where its sums differ from the canvass, the canvass is right. It has the 2022 governor, attorney general, secretary of state, comptroller, treasurer and U.S. Senate races by county and the 2024 presidential race. The Board’s own Vote Totals files would have to be saved by a person in a browser, or provided by the Board, before they can replace it, and for 2026.
- The contests on this board come from the Board’s calendar and Capitol News Illinois (November 4, 2026), not from the Board’s candidate list. The U.S. Senate seat is open: Senator Dick Durbin announced in April 2025 that he would not seek another term (NBC, WTTW and Axios; not confirmed from a Board candidate list).
- The State Senate is not listed. About 39 of its 59 seats are up in 2026 (Ballotpedia and WBEZ, October 1, 2026), but we have not confirmed which districts from a Board list, so we do not guess.
The state page lists results from approved rows drawn from state results feeds and Wikipedia; those are not the counts on this desk, which shows no 2026 result because the State Board of Elections’ site cannot be read by automated tools; its 2022 and 2024 numbers are from a secondary source. See the state page.
- Democratic
- Republican
