According to the Brennan Center for Justice, half of US states have adopted hundreds of harsh measures making it more difficult for American citizens to vote. The new laws range from strict photo ID requirements to early voting cutbacks to registration restrictions.
Overall, 25 states have put in place new restrictions since then — 15 states have more restrictive voter ID laws in place (including six states with strict photo ID requirements), 12 have laws making it harder for citizens to register (and stay registered), ten made it more difficult to vote early or absentee, and three took action to make it harder to restore voting rights for people with past criminal convictions.
In 2016, 14 states had new voting restrictions in place for the first time in a presidential election. Those 14 states were: Alabama, Arizona, Indiana, Kansas, Mississippi, Nebraska, New Hampshire, Ohio, Rhode Island, South Carolina, Tennessee, Texas, Virginia, and Wisconsin.
In 2017, legislatures in Arkansas and in North Dakota passed voter ID bills, which governors in each state signed, and Missouri implemented a restrictive law that was passed by ballot initiative in 2016. (Texas also passed a new voter ID law, though its earlier strict voter ID law was partially in effect in 2016.) Georgia, Iowa, Indiana, and New Hampshire also enacted restrictions last year, in addition to laws that were on the books for previous elections
In 2018, Arkansas, Indiana, Montana, New Hampshire, North Carolina, and Wisconsin enacted new restrictions.
In 2019, Arizona, Florida, Indiana, Tennessee, and Texas have enacted new restrictions.
