Voters face a closely contested decision on Question 3, the citizen-initiated measure that would replace separate Democratic and Republican primaries for state and congressional offices with a single all-party primary where the top two candidates advance to the general election starting in 2028. Trader sentiment reflects a narrow edge for passage amid divided Democratic support—some moderate lawmakers back the change for broader voter input in a heavily Democratic state—while both major party organizations and many elected officials oppose it over concerns that it reduces party roles in candidate selection and could produce same-party general election matchups. The Supreme Judicial Court cleared the measure for the ballot in June after legal challenges, and active campaigns by reform groups and opponents continue into early voting. Recent polling trends, turnout patterns among unenrolled voters, and last-minute endorsements or advertising could shift the implied probability in either direction before November 3.
