Greenhouse is a browser plugin created by Nicholas Rubin, a 16-year-old programmer. It seeks out the names of elected US officials on any web-page you load in your browser and adds a pop-up link to their names listing the major donors to their campaigns. It uses 2012 election-cycle data drawn from Opensecrets's repository.
I've long suggested something like this as a way of improving political coverage. Indeed, you could imagine it going both ways — any time the name of a company or individual who had made some big campaign contributions shows up in a webpage, you get a list of their political beneficiaries. Ideally, this would be an open framework to which data from any political race could be added.
It is my hope that providing increased transparency around the amount and source of funding of our elected representatives may play a small role in educating citizens and promoting change. If you use the extension when reading about a Congressional vote on energy policy, for example, maybe you'll discover that a sponsor of a bill has received hundreds of thousands of dollars from the oil and gas industry. Or maybe you'll learn that the top donors to a member of Congress who opposes tort reform are lawyers and law firms. I use data from the last full election cycle (generally 2011-12 for Representatives and 2007-12 for Senators) and plan to update it as more relevant data becomes available. Special thanks to OpenSecrets.org for providing access to that data.
The motto of Greenhouse is: "Some are red. Some are blue. All are green." What it signifies is that the influence of money on our government isn't a partisan issue. Whether Democrat or Republican, we should all want a political system that is independent of the influence of big money and not dependent on endless cycles of fundraising from special interests. The United States of America was founded to serve individuals, not big interests or big industries. Yet every year we seem to move farther and farther away from our Founders' vision.
