Mariana Leitão in the polls: approval history and what happened

The thick line is the 30-day average: only the latest poll from each available pollster counts, with equal weight. Each dot is a published poll, on the day its fieldwork ended. The ring and the home page show the latest value of this average. In the filters you can also show disapproval and each pollster's line, pick a single pollster or a period. The marked rises and falls are worked out pollster by pollster, and we do not compare countries: each chart has its own question. Hover over (or tap) a dot to see the pollster.
