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.
• 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.
