The Brennan Center for Justice, tireless proponents of voting rights, have published a new updated “Voting Laws Roundup 2016.”
As they report:
At the beginning of the 2016 legislative session, and as of March 25, 2016, at least 422 bills to enhance voting access were introduced or carried over in 41 states plus the District of Columbia. Meanwhile, at least 77 bills to restrict access to registration and voting have been introduced or carried over from the prior session in 28 states.”
Notably, they find that “. . . restrictions in 17 states will be on the books for the first time in a presidential election in 2016.”
You can find the details on those restrictions here.
