538 Election Status Icon
Simple Chrome extension to take the 2016 Nate Silver presidential election model output and put it in in a tiny icon in your Chrome toolbar.
It's also not a bad example of the very minimum it takes to make a useful Chrome Extension with a "browser action."
How does it work?
A background script periodically hits the FiveThirtyEight website and pulls down a page containing results data. From that, it scrapes out the top-level predictions for each candidate, updates the status icon, and stores them.
If the user clicks on the status icon, a bit more of the results are shown in a popup.
