From Wired:
Tread carefully, politicians — concerned citizens are watching your every move on the web. Their tools? Custom data mashups that use public databases to draw correlations between every vote cast and every dollar spent in Washington. . .
. . . Anyone — from bloggers and students to lobbyists and activists — can use these sites to quickly drill down into the correlation between a politician’s vote and the money he or she received from special interests. The graphs and reports are easily shared or posted on a blog. The sites give access to data by legislator, bill number, bill subject or special interest.
