General election race ratings

See also: Race rating definitions and methods

Ballotpedia provides race ratings from four outlets: The Cook Political Report, Inside Elections, Sabato's Crystal Ball, and DDHQ/The Hill. Each race rating indicates if one party is perceived to have an advantage in the race and, if so, the degree of advantage:

  • Safe and Solid ratings indicate that one party has a clear edge and the race is not competitive.
  • Likely ratings indicate that one party has a clear edge, but an upset is possible.
  • Lean ratings indicate that one party has a small edge, but the race is competitive.[1]
  • Toss-up ratings indicate that neither party has an advantage.

Race ratings are informed by a number of factors, including polling, candidate quality, and election result history in the race's district or state.[2][3][4]

Post-filing deadline analysis

The following analysis covers all U.S. House districts up for election in Illinois in 2026. Information below was calculated on Nov. 3, 2025, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.

One hundred five candidates — 69 Democrats and 36 Republicans — ran for Illinois’ 17 U.S. House districts. That’s 6.2 candidates per district. There were 2.7 candidates per district in 2024, 5.6 in 2022, 4.1 in 2020, 4.4 in 2018, 2.7 in 2016, and 2.8 in 2014.

This was the highest total number of candidates who ran for the U.S. House since 2014.

Five districts were open in 2026. There were no districts open in 2024, four in 2022, one in 2020, one in 2018, one in 2016, and none in 2014. Reps. Jesus Garcia (D-4th), Danny K. Davis (D-7th), and Jan Schakowsky (D-9th) retired from public office. Reps. Raja Krishnamoorthi (D-8th) and Robin Kelly (D-2nd) ran for the U.S. Senate.

Twenty primaries — nine Democratic and 11 Republican — were contested in 2026. In total, there were 11 contested primaries in 2024, 19 in 2022, 21 in 2020, 20 in 2018, 14 in 2016, and nine in 2014.

Twenty candidates — 16 Democrats and four Republicans — ran for the open 9th district, the most candidates that ran for a district in 2026.

Five incumbents — four Democrats and one Republican — faced primary challengers in 2026. There were five incumbents in a contested primary in 2024, seven in 2022, 10 in 2020, seven in 2018, seven in 2016, and three in 2014.

Candidates filed to run in the Republican and Democratic primaries in all 17 districts, meaning no districts were guaranteed to either party.
