Donna Miller secured the Democratic nomination in March 2026 for Illinois’s 2nd Congressional District after winning a crowded primary with 40.4% of the vote, outpacing notable challengers including Jesse Jackson Jr. The open seat, previously held by retiring Rep. Robin Kelly, sits in a district with a strong Democratic lean reflected in its partisan voting index and consistent past results. Republican nominee Michael Noack advanced unopposed in his primary but has reported no campaign fundraising, limiting visibility and organization ahead of the November 3 general election. Election forecasters rate the race as safe or solid Democratic. Trader consensus heavily favors Miller given the district’s composition, her primary performance, and the absence of meaningful Republican resources or recent developments that would narrow the gap. Late-breaking events such as a significant scandal or health-related withdrawal remain the primary, though low-probability, factors that could alter the outcome.
