How this is built
Question 3 is forecast as a elections measure whose Yes vote leans to neither party. Comparable measures from 2018 to 2024 set how far its Yes share moves with Massachusetts's partisanship and with each county's 2024 presidential vote, and how it reached the ballot moves it further. Polls then pull the forecast toward them by recency and size, after splitting undecided voters two to one for No. Sources: sec.state.ma.us, boston.com, nbcboston.com, commonwealthbeacon.org.
