Editorial raters moved while polling has gone quiet

  • 2016d old
    Poll was fielded 2016 days ago. Older polls reflect an earlier state of the race and are weighted down in the rolling average.
  • ✓ verified 5d ago
    auto-checked on 5/4/2026. Deterministic checks confirmed bounds + structure (percentages in [0,100], totals plausibly close to 100%, dates ordered). Source page itself was not re-fetched.
  • likely-voter screen
    Likely-voter screen — pollster filters respondents by reported turnout intent. Generally tighter for predicting elections than registered- or adult-population polls.
  • bias D+1.5pt
    Across 49 historical scored polls the average error vs. actual margin is D+1.5pt.
  • tracks editorial consensus
    Across 53 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.
