Rootstrikers is a nonpartisan grassroots activist organization run by Demand Progress and created by Harvard Law School professor Lawrence Lessig[1][2] and political activist Joe Trippi (a Democratic campaign worker and consultant) for the purpose of fighting political corruption in the United States and reducing the role of special interest money in elections.

In September 2012, Rootstrikers reorganized under the umbrella of Fund for the Republic, a 501(c)(3) organization dedicated to challenging the influence of money in American politics.

[8] The name "Rootstrikers" is based on a quote from the first chapter of Henry David Thoreau's book Walden:[1][9] "There are a thousand hacking at the branches of evil to one who is striking at the root".

[14] Rootstrikers is one of 15 organizations in the Money Out / Voters In coalition that sponsored "A 28th Amendment" conference at the UCLA School of Law, Saturday, November 17, 2012.

Of the proposed amendments, five were identified as primarily attempting to limit the constitutional rights of corporations; the other 16 were described as dealing more with campaign finance, though there is overlap.
