Rhode Island Polling Transparency Review
Pell Center / Embold Research — October 5–8, 2026
Embold Research reports surveying 815 likely Rhode Island voters. Its methodology statement says 452 respondents were recruited through targeted Facebook, Instagram, and web advertising and 363 through text messages sent to voter-file telephone numbers.
The statement further says Embold used dynamic online sampling during fielding: lowering advertising budgets for groups it considered overrepresented, raising budgets for groups it considered underrepresented, and texting underrepresented groups as needed. The completed sample was then post-stratified by age, gender, race/ethnicity, education, 2024 presidential vote, and region.
The methodology reports a 3.6% modeled margin of error and says its effective sample size accounts for the design effect of weighting.
