New UMass Amherst / WCVB Poll Finds Healey, Diehl Running Away with Party Nominations for Massachusetts Governorship.
On the day Sonia Chang-Díaz drops out of Democratic race, the new poll found her trailing AG Maura Healey by over 30 points, while the primary race for lieutenant governor is a three-way toss-up entering the summer campaign season.
YouGov interviewed 1131 Massachusetts respondents who were then matched down to a sample of 1000 to produce the final dataset. The respondents were matched to a sampling frame on gender, age, race, and education. The frame was constructed by stratified sampling from the full 2019 American Community Survey (ACS) 1-year sample with selection within strata by weighted sampling with replacements (using the person weights on the public use file).
The matched cases were weighted to the sampling frame using propensity scores. The matched cases and the frame were combined and a logistic regression was estimated for inclusion in the frame. The propensity score function included age, gender, race/ethnicity, and years of education. The propensity scores were grouped into deciles of the estimated propensity score in the frame and post-stratified according to these deciles. The weights were then post-stratified on 2016 and 2020 Presidential vote choice, own/rent, gender, age, race, and education to produce the final weight.
