The Center for American Progress and the American Constitution Society are marking the second anniversary of the Supreme Court’s Citizens United decision by hosting a discussion on the role corporate money will play in the 2012 election season.

Two years ago, the Supreme Court ruled that corporations may spend freely to support or oppose candidates for president and Congress, easing decades-old limits on their participation in federal campaigns.

At the event, E.J. Dionne, a Washington Post columnist and Senior Fellow at the Brookings Institution, will moderate a discussion with leading thinkers and advocates about the future of campaign finance reform as well as the latest developments on efforts to amend the Constitution to reverse the Supreme Court’s holding that corporations are people with free speech rights.
