Republican voter suppression is rampant. Manchin and Sinema are complicit now | Moira Donegan

Manchin and Sinema's intransigence on the filibuster helps the Republican party usher in an era of voter suppression and election subversion

The last chance for federal legislation to stem the tide of Republican state-level attacks on the franchise died this week, when Senators Joe Manchin and Kyrsten Sinema rejected a bid by the Senate's Democratic majority to change the filibuster rules to allow the passage of two voting rights bills.

The Freedom to Vote Act and the John Lewis Voting Rights Act would together serve to establish a baseline of federal rules enabling access to the ballot in all 50 states, and would restore the congressional authority to oversee new election laws in states that have a history of racist voting restrictions - a civil rights-era provision that was gutted by the Republican-controlled supreme court. But the two bills have been blocked repeatedly by Senate Republicans, who have used the chamber's supermajority rule to prevent them from coming to a vote.
