No scientific polls in the last 30 days — the figure is the last three qualifying polls of the locked matchup, or fewer when fewer exist, not a 30-day mean. The table lists the polls in that average, plus the most recent 30 days or the newest 3 polls, whichever is more. How accurate is each pollster? →
