Incumbent Democrat Mike Quigley secured the Democratic nomination in Illinois' 5th Congressional District's March 17 primary with 66% of the vote, defeating three challengers amid low turnout in this reliably blue North Side Chicago seat with a D+18 Cook Partisan Voting Index. Republican nominee Tommy Hanson, a perennial candidate who has repeatedly lost to Quigley, advanced unopposed in his primary, reinforcing trader consensus on a Democratic hold reflected in 93% implied probability. The district's entrenched Democratic voting blocs and Quigley's long tenure since 2009 underpin this dominance, though a major scandal, Quigley's health issues, or an overwhelming national Republican wave could narrow the path to victory ahead of the November 3 general election.
