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.^[5]
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.^[6]^[7]^[8]

Post-filing deadline analysis

The following analysis covers all U.S. House districts up for election in Massachusetts in 2024. Information below was calculated on June 27, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.

Thirteen candidates ran for Massachusetts’ nine U.S. House districts, including nine Democrats and four Republicans. That’s an average of 1.44 candidates per district. There was an average of 2.11 candidates per district in 2022, 3.00 candidates per district in 2020, and 3.44 candidates per district in 2018.

The number of candidates who ran for the U.S. House in Massachusetts in 2024 was also fewer than any other year in the last 10 years. Between 2014 and 2022, an average of 22.2 candidates ran per election cycle.

No districts were open in 2024, meaning all incumbents ran for re-election.

Four candidates—one Democrat and three Republican—ran for the 8th Congressional District, the most candidates who ran for a district in Massachusetts in 2024.

The Republican primary in the 8th Congressional District was the only contested primary in 2024. Between 2014 and 2022, an average of 3.4 were contested each election cycle.

No incumbents were in contested primaries in 2024.

Democrats were guaranteed to win seven of the state's nine U.S. House districts because no Republicans filed to run. Candidates filed to run in the Republican and Democratic primaries in the 8th and 9th Congressional Districts, meaning neither seat was guaranteed to either party.
