Massachusetts's deep Democratic partisan lean and unbroken streak of Democratic Senate victories since 2010 anchor the heavy market preference for a Democratic nominee. Incumbent Ed Markey holds a consistent lead in recent Democratic primary polling against challenger Seth Moulton, while Republican primary candidates remain low-profile and face structural headwinds in a state where registered Democrats outnumber Republicans by wide margins. Forecasters rate the seat solid or safe Democratic based on historical turnout patterns and limited crossover appeal. Trader consensus at these levels reflects the absence of major scandals, health developments, or national shifts that could narrow the gap before the November general election.

A candidate shall be considered to represent a party in the event that he or she is the nominee of the party in question. Candidates other than the Democratic or Republican nominee (e.g., Greens, Libertarian, independent) may be added at a later date.
Candidates who run as independents will not be encompassed by the “Democrat” or “Republican” options regardless of any affiliation they may have with the party.
