Nicholas Rubin, a 16-year-old programmer from Seattle, has created a browser add-on that makes it incredibly easy to see the influence of money in US politics. Rubin calls the add-on Greenhouse, and it does something so brilliantly simple that once you use it you’ll wonder why news sites didn’t think of this themselves.
Greenhouse pulls in campaign contribution data for every Senator and Representative, including the total amount of money received and a breakdown by industry and size of donation. It then combines this with a parser that finds the names of Senators and Representatives in the current page and highlights them. Hover your mouse over the highlighted names and it displays their top campaign contributors.
