Cavendish Cymru Senedd Seat Projector.
Welcome to the Cavendish Senedd Seat Projector. This unique tool allows you to enter the latest polling and it will project the results of the 2026 Senedd Election. It uses the uniform national swing model. The baseline is the 2024 General Election, so it reflects the new seat boundaries as well as the new electoral system.
The map shows the projected seat outcomes based on the percentage of the vote you have entered. The first seat allocated by the d’Hondt system is at the top of the coloured rod on the map. Scroll down to see the results tabled.
This tool allows you to enter the latest opinion poll or make your own predictions for the overall percentage of the vote that you think a party will receive at the next Senedd Election.
