I’ve compiled this Google Doc, that I’ll update as things progress this evening.
It shows all pre-election polls, forecasts and poll-of-poll averages that I know of. For each poll/forecast/average it will also calculate the deviation for each party and across all results.
A few notes:
- I’m very sorry if I’ve made a numerical error. Please let me know and I’ll fix it up.
- In 2014, the final/official election result (released a month or so after Election Day) made quite a big difference when it came to the predictive accuracy of each poll. Please take these results as they are intended – a bit of fun on Election Night.
