Madison is an online platform for crowdsourcing legislation for consideration by the US House of Representatives. It provides citizens with a way to give direct feedback on policy documents online and gives lawmakers a powerful way to understand the needs of the people they represent and to harness the collective knowledge of their communities. Madison addresses the fact that most Americans do not have a say in the policies that affect their lives at the city, state, or federal level. Few citizens have the time or resources to track legislation, appear in person at public hearings, and prepare formal testimony — or even to know what their elected officials are working on. And, overworked and under-resourced lawmakers do not have an efficient or effective way to ensure that the policies they create best meet the needs of their communities. Madison was used to create the first two pieces of crowdsourced legislation in the history of the US Congress: the DATA Act, which was signed into law on May 9, 2014, and FISMA, the Federal Information Security Management Act of 2012, which marked the first time a member of the US Congress solicited online public input on legislation.
