This article from the National Conference of State Legislatures magazine, entitled "The Transparency Trend" (scroll down), reports:
"Almost a third of online Americans surveyed in a recent poll are searching the Internet for information about how the government generates and spends taxpayer dollars, and most are disappointed, according to a recent Association of Government Accountants study. The study also showed that almost half of those surveyed are not satisfied with the information they receive about their state’s financial management. They want understandable and timely information, and they want to be educated about state budget challenges."
Washington has a good law on this.
