Zephyr got in touch with me today to ask about helping out with some UI for an organization she's now involved in. Poking around their site, I found this screencast showing how to use a site called "opensecrets.org" to find out who has been making what kinds of contributions and to whom, in U.S. election campaigns.
While not surprising, the information it presents is eye opening. Just click through the "Sector" overviews and marvel at the divisions of who donates to whom, when.
That said, the data is there; it is publicly available. It could however use some massaging and some highlighting and some contextualizing and pre-chewing for a wider audience (make it something someone can broadcast, not something some small group of people have to look up if the thought of doing so strikes them.)
Please do check it out.
