New UMass Amherst / WCVB Poll Finds Some Leads Widening, Others Vanishing in Mass. Democratic Party Primary Down-ballot Races.
As Maura Healey cruises to her party’s nod for governor, Democratic voters energized by the Supreme Court’s recent abortion decision express overall satisfaction with the slate of candidates, even if they might be undecided in some races.
YouGov interviewed 547 respondents who were then matched down to a sample of 500. The respondents were matched to a sampling frame on gender, age,race, and education. The frame was constructed by stratified sampling from the from the 2020 Cooperative Congressional Election Study with selection within strata by weighted sampling with replacements.
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 own/rent, gender, age, race, and education to produce the final weight.
