(Bobby Rush (D) is retiring.)
District 2
Robin Kelly (D-inc) vs. Thomas Lynch (R)

District 4
Chuy Garcia (D-inc) vs. James Falakos (R), Edward Hershey (Working Class)
District 5
Mike Quigley (D-inc) vs. Tommy Hanson (R), Jerico Matias Cruz (I)
District 6
Sean Casten (D-inc) vs. Keith Pekau (R)
Analysis: Casten won over Marie Newman in an incumbent-vs.-incumbent primary. Unlike many affluent suburban areas in the country, this district did not trend Democratic as much. Casten has the advantage, but it will be close.
Outlook: Lean Casten (Democratic hold)
District 7
District 8
Raja Krishnamoorthi (D-inc) vs. Chris Dargis (R)
District 9
Jan Schakowsky (D-inc) vs. Maxwell Rice (R)
District 10

Bill Foster (D-inc) vs. Catalina Lauf (R)
District 12
Mike Bost (R-inc) vs. Chip Markel (D)
District 13
Nikki Budzinski (D) vs. Regan Deering (R)
Analysis: This is a new seat, created to take in the Democratic-leaning areas in central and southern Illinois. Turnout in these areas tends to drop dramatically in midterms, so this district could go either way.
Outlook: Lean Budzinski (Democratic gain)
District 14
Lauren Underwood (D-inc) vs. Scott Gryder (R)
Analysis: Underwood’s district was made more Democratic, but she could still face a competitive race in a Republican-leaning environment.
Outlook: Likely Underwood (Democratic hold)
District 15
Mary Miller (R-inc) vs. Paul Lange (D)
District 16
Darin LaHood (R-inc) vs. Elizabeth “Lisa” Haderlein (D)
District 17
Eric Sorensen (D) vs. Esther Joy King (R)
Cheri Bustos (D) is retiring. This district voted for Donald Trump in 2016 but was made slightly more Democratic. The environment makes this race one to watch.
Outlook: Lean King (Republican gain)
State Elections
Governor
J.B. Pritzker (D-inc) vs. Darren Bailey (R), Scott Schluter (L), Tommy Belg (I)
Outlook: Strong Pritzker (Democratic hold)
