  • no scored polls
    Pollster has no historical polls with a known outcome in our database, so accuracy and bias cannot be measured.
  • 599d old
    Poll was fielded 599 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.
