Older polls reflect an earlier state of the race and are weighted down in the rolling average. uncorrelated with editorial consensus Across 49 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.
