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.[2]
- 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.[3][4][5]
