Jennifer Davis

Open seat -- the current officeholder is a Democrat, Raja Krishnamoorthi, who is not running (running for U.S. Senate).
Why we think this
- This district's baseline partisan lean favors Democrats by about 6 points of margin before anything else is considered.
- This is an open seat: the current officeholder (a Democrat, Raja Krishnamoorthi) is not on the ballot, which tends to make the race more competitive than a defended seat.
