"This year marks the first presidential election in 50 years without a functioning Voting Rights Act — and it’s not going well. Republican lawmakers have been devising efforts to make it harder for Americans to vote for many years, since the GOP took over statehouses across the country in 2010. Those efforts culminated in 2013 with the Supreme Court’s decision to strike down key portions of the Voting Rights Act (VRA), a formerly untouchable cornerstone of civil rights. For the past three years, states and jurisdictions have no longer had to clear potentially discriminatory laws with the Department of Justice — at least not as long as a Congress controlled by radical, right-wing factions continues to sit on the rewrite of the VRA."
