MAPlight.org does great things with using the Internet to shine daylight into issues of money and politics. Their latest offering are widgets that track the fundraising of presidential candidates (which is a little too horserace-oriented for my taste). You can customize them with the candidates of your choosing. I made one (below) showing all of the candidates, sorted by the amount raised. The main lesson I take from it is that billions of dollars are being wasted on TV ads and manipulative consultants. And that Edwards is at the top of the second tier instead of at the bottom of the top tier where I would like him to be.
