Illinois Law dean and professor Vikram David Amar examines California’s Proposition 49—which seeks the voters’ approval for the California legislature to ratify an amendment to the federal Constitution to overturn the U.S. Supreme Court’s 2010 decision in Citizens United v. FEC—in order to shine light on what might be required to overturn the decision on a federal level. Amar argues that Proposition 49 highlights just how difficult it would be to craft a workable constitutional amendment to overturn Citizens United.
