Millions of US voters lack access to documents to prove citizenship

New study reveals number of people potentially affected by Republican efforts to prevent non-citizen voting'

Nearly one in 10 eligible voters lack easy access to documents to prove their citizenship, according to a new survey, underscoring how Republican efforts to purportedly prevent non-citizens from voting could disenfranchise millions.

If asked to quickly locate a passport, birth certificate, or naturalization papers to produce proof of citizenship tomorrow, more than 21m Americans - about 9% of eligible voters - would not be able to, according to the survey, conducted by the Brennan Center for Justice, VoteRiders, Public Wise, and the Center for Democracy and Civic Engagement (CDCE) at the University of Maryland. Nearly 4 million American citizens - 2% in total - lack access to any form of proof in citizenship.
