weight 0.27 Aggregation weight is 0.27 (1.0 ≈ average). Weight combines historical accuracy, methodology, and recency. - 🟡
3 scored polls Pollster has only 3 historical polls with a known outcome to score against — too few for stable accuracy estimates. - 🟡
adult sample Adult-population sample (no voter screen) — useful for general public opinion but not directly comparable to LV polls for predicting elections. - 🟡
1292d old Poll was fielded 1292 days ago. Older polls reflect an earlier state of the race and are weighted down in the rolling average. - ⚪
