Massachusetts Reports 2026 Lieutenant Governor Primary Results as Vote Estimates Shift

Q: Will a new ballot initiative permanently erase the unique Massachusetts tradition of holding separate lieutenant governor primaries?

Not yet. Massachusetts is still using its distinctive system in 2026, with a separate primary for lieutenant governor and governor nominees later paired into a joint ticket for November. That could change if voters approve Question 3, also known as Initiative 25-12. The measure would replace separate party primaries with an all-party, top-two primary for statewide, legislative, congressional and some county and district offices. Under that system, candidates for governor and lieutenant governor would run together as a ticket in the primary, which would effectively end the state’s separate lieutenant governor primary tradition. But the change is not automatic or guaranteed. The proposal was only cleared for the November 2026 ballot after the Massachusetts Supreme Judicial Court rejected a legal challenge. Voters still must approve it in November for it to take effect. Public polling suggests the measure has a plausible path, but not a certain one. A UMass Amherst/WCVB poll found 51% support, 32% opposition and 17% undecided. Supporters say the change would open the process to all voters and increase competition in a state where many races go uncontested. Opponents argue Massachusetts already allows unenrolled voters to participate and warn the new system could make campaigns more expensive and shift influence toward better-funded candidates. So the answer is yes only if Question 3 passes. Until then, the separate lieutenant governor primary remains in place.

Q: How do predictive models accurately call a race when 100,000 mail-in ballots are still missing from the final count?

A race can be called before every ballot is counted because projection teams are not waiting for a final total; they are judging whether the remaining uncounted ballots could realistically change the outcome. NBC News says it uses verified vote tallies from local officials, AP data, and its Decision Desk’s estimate of the “expected vote,” which is a running estimate of how many ballots will ultimately be counted. The key is that “100,000 mail ballots outstanding” does not mean 100,000 unknown votes are likely to break evenly or all count in the same race. Analysts know where those ballots are coming from, how many have already been returned, which counties or cities still have large backlogs, and how similar ballots have been voting so far. They also compare the leader’s margin with the size and likely partisan or geographic profile of the remaining vote. If the trailing candidate would need an implausibly large share of what is left, the race can be projected. These models also account for ballot type. Early in-person, election-day, and mail ballots often have different patterns, and election desks build those patterns into their estimates. They update projections as local officials report more information, which is why NBC notes the expected-vote figure can change. In short, the call is not based on guessing the exact final number. It is based on whether the outstanding ballots leave any credible mathematical path for the trailing candidate to overtake the leader.

Live results are being reported in the 2026 Massachusetts lieutenant governor primary, which will decide each party’s nominee for the statewide office.
Expected vote totals are estimates rather than final counts, based on early-vote data and Election Day information gathered from county election officials.
NBC News said those estimates can change as new information comes in, while vote data are supplied by the Associated Press and projections come from the NBC News Decision Desk.
