A handy new tool is available for people interested in keeping a close eye on campaign contributions. Illinois Comptroller Judy Baar Topinka has launched the "Open Book" database, which let's you follow the money in campaigns. The database compares state contracts with campaign contributions and gives users a portal of transparency in state government. It lists every dollar donated and combines information from the Comptroller's accounting system with the Illinois State Board of Elections semi-annual campaign finance disclosure reports.
