Incumbent Democrat Ed Markey holds a commanding position in trader consensus for the Massachusetts Senate race, with recent polls like the University of New Hampshire survey from mid-February showing him leading likely Republican John Deaton 56%-27% and primary challenger Seth Moulton prevailing 59%-23% in a general matchup. Massachusetts' deep-blue history—no Republican senator elected since 1978—combined with Markey's incumbency and fresh endorsements such as the Human Rights Campaign's backing this week, underpin the 94.5% implied probability for a Democratic winner ahead of the September 1 primaries. While GOP filings remain sparse with only Deaton and Nathan Bech declared, scenarios like a high-profile Republican recruit, Markey's health concerns at age 80 prompting retirement, or a divisive Democratic primary weakening the nominee could narrow the gap before November 3.
