Data: The Annenberg Constitution Day Civics Survey, August 9-13, 2017, 1,013 respondents; Chart: Chris Canipe / Axios

"More than half of Americans (53%) incorrectly think it is accurate to say that immigrants who are here illegally do not have any rights under the U.S. Constitution," according to the Annenberg Constitution Day Civics Survey, by the Annenberg Public Policy Center at the University of Pennsylvania.

37% of the 1,013 adults surveyed (37%) can't name any of the rights guaranteed under the First Amendment. Why it matters, from Kathleen Hall Jamieson, the center's director: "Protecting the rights guaranteed by the Constitution presupposes that we know what they are."
