Pollytrack is a weekly aggregation of federal political polling, making it the most theoretically accurate tracking poll in the country.
Each Pollytrack calculation is made up of a rolling all pollster average weighted by sample size, that operates over a 5 week maximum window, and where each pollster has only one poll contributing to the super sample at any given time.
As a pollster releases a new poll, their old poll result drops out of the rolling window, and gets replaced by their new polling data. If a pollster releases no new polling data within 5 weeks of their previous poll, their polling drops out of the Pollytrack window completely.
The 5 week window works best as ACNielsen (a monthly pollster) occasionally releases polls 5 weeks apart rather than the usual 4, simply because of timing issues. Using a 5 week window allows us to nearly always have an Nielsen poll in the Pollytrack mix.
The beauty of this is that it gives us super samples that you can read off the charts below as well as minimum MoEs running between 1.1% and 1.5% (which are the vertical bars attached to the Pollytrack polling lines). The details of the polls that make up the current Pollytrack can be read from the sidebar on the right.
