  • n=2,120
    Sample size of 2,120 respondents implies a margin of error around ±2.1pt — tighter than the ~600-respondent typical.
  • tracks editorial consensus
    Across 12 historical paired polls, this pollster's D-margins track the rater consensus (Cook / Sabato / IE / 538 / DDHQ etc.) with high correlation (r ≥ 0.85) and small mean delta (|Δ| ≤ 2pt). Their results align with conventional wisdom.

    Across 368 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.
