\u201cFollow the money - and it\u2019ll lead you to the truth\u201d. That\u2019s the advice given to reporters investigating the Watergate scandal in the movie All The President\u2019s Men.\n\nThe advice still applies, though it\u2019s much harder to track money flow in politics today. How do you track who donated to whom? Who\u2019s lobbying for what? What legislation may be influenced?\n\nData analytics, visualization and new datasets help analyze how money and lobbying influence politics.\n\nTrue Blood\n\nSynthetic blood is invented in this fictional TV series set in rural Louisana. This allows vampires to "come out of the coffin" and allow their presence to be known to mankind. Vampires struggle for equal rights and assimilation, while anti-vampire organizations begin to gain power. In this scenario, imagine that legislation is being proposed to lower the prices of \u2018true blood\u2019.\n\nHow do you find out who is behind this lobbying effort? How much have vampires donated to politicians to advocate for the bill? Which political action committees (PACs) are involved? As with vampires, much of this would be done in the \u2018dark\u2019. (This is a fictional example, and to the best of my knowledge there is no such legislation being sponsored by vampires).\n\nSearching for the truth\n\nMapLight provides a database that combines lawmakers\u2019 votes, groups supporting and opposing legislation, and campaign contributions. The database has over 30 million records, including campaign finance data, legislative voting data, interest group support and opposition data. It provides transparency tools for searching, sorting, visualizing, and finding connections within this database. This allows users to analyze how campaign contributions affect policy. Some of the analysis and visualization tools offered include:Total Contributions: Compares campaign contributions from interest groups that support a bill with contributions from interest groups in opposition.Contributions by Vote: Correlates interest group contributions with how lawmakers vote.Timeline of Contributions: Shows when a campaign contributions is received relative to a vote.Topic Pages: Search for and track bills by issue area.Company Pages: Profiles top-contributing companies, according to the total contributions made, documented bill positions they have taken, and bill positions they have "won."Contributions Search: Find out who gave what to whom and when.\n\nDark Money\n\n\u201cWhen donors give money directly to a campaign, political party, or super PAC, their names and the amounts they have given must be disclosed. Dark money is different. It comes from groups\u2014typically limited liability corporations (LLCs) or politically active nonprofits\u2014that do not have to disclose their donors. As a result of U.S. Supreme Court decisions in 2007 and 2010, those groups can receive unlimited amounts of money from individuals, corporations, and other organizations. They can then use that money to pay for television ads and other efforts to influence voters. Often the public doesn't know who is funding those efforts\u201d, explains Daniel Newman, President and Co-Founder of Maplight.\n\nResources\n\nThese five sites provide data sources, analysis and visualization tools to track the role of money in politics.Little Sis - a project by Public Accountabillity Initiative.
