How this is built
Question 5 is forecast as a income tax measure whose Yes vote leans Republican. 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.
