Many GOP states have imposed new voting rules this year, some mirroring Trump's midterm proposals | The Associated Press

Voters in more than 20 states will be faced this year with new laws for registering to vote and casting ballots. Nearly 40 laws are taking effect for the first time in this year's midterms, mostly in Republican-controlled states. Many of them mirror changes President Donald Trump tried but failed to implement at the national level, including voter ID rules or requirements for people to show documents proving U.S. citizenship when registering to vote.
