Polls dominate election coverage but are routinely misunderstood — by readers, by journalists, and sometimes by the people who commission them. These long-form guides explain how polling actually works, why the headline numbers can mislead, how electoral systems shape what a poll can tell you, and how to read averages and trends with the humility they deserve. All articles are written by the Democracy Pulse editorial team and intended as evergreen reference material.
