**The closely matched leading bins around 2.65M–2.95M votes reflect uncertainty in an uncompetitive general election where Democratic incumbent Ed Markey holds a roughly 20-point polling lead over Republican John Deaton in a solidly blue state.** A lopsided Democratic primary won by Markey over Seth Moulton produced limited enthusiasm, consistent with Secretary of State William Galvin’s assessment that it would not generate unusually high participation. Typical midterm turnout drop-off, combined with reliance on early and mail ballot volumes in a low-stakes race, keeps trader assessments clustered without clear separation. Historical patterns from recent midterms and the absence of major catalysts or national events that could mobilize additional voters sustain the tight distribution across the central ranges.
