Hey California voters! Curious about how much beverage company cash helped influence a vote on bottled-water standards? Wondering which interest groups are especially generous to your state Assembly member? Check out this new online money-and-politics database from Maplight.org, a Berkeley-based non-profit. It tracks votes on specific bills by state pols and cross-references that info with details on who gave them money, and when. So far, only data from 2003-2004 is available, but the Maplighters claim more recent stuff will be up soon. The impatient can do their own state-level research with the help of The Institute on Money and State Politics , or go federal at OpenSecrets.org. And of course there's always the famous Mother Jones 400, one of the very first online sources of campaign finace dirt.
