Since launching in September, May2015 has tried to become a home for all the election data you might need. We began with a ‘Poll of Polls’ to keep on top of the 10-11 polls coming out each week. Then we used a version of uniform swing to turn that into a seat prediction.
In December we added ‘The Drilldown’: our unique insight into the polls, which allows you to break down voters’ attitudes to the economy, government and different issues by age, class, gender and political ID.
