commissioned by D-aligned: Internal D-alignedno scored polls+2
  • commissioned by D-aligned: Internal D-aligned
    This poll was commissioned by a Democratic-aligned committee, party, or PAC (Internal D-aligned). Such polls historically lean toward their sponsor.
  • no scored polls
    Pollster has no historical polls with a known outcome in our database, so accuracy and bias cannot be measured.
  • uncorrelated with editorial consensus
    Across 17 historical paired polls, this pollster's margins don't track the editorial consensus (Pearson r < 0.5). Independence from consensus is informational — could indicate genuine methodological independence or noisy results.
  • likely-voter screen
    Likely-voter screen — pollster filters respondents by reported turnout intent. Generally tighter for predicting elections than registered- or adult-population polls.
