All 50 Republican senators voted Wednesday to block debate on a federal voting rights bill that would rein in voter suppression laws passed by Republican-led state legislatures. It’s the third time this year that Senate Republicans have used the filibuster to block voting rights legislation. The Freedom to Vote Act was already a compromise that scaled back voter protections under the For the People Act, after conservative Democratic Senator Joe Manchin said he would oppose that bill. The latest move by Republicans to stonewall voting rights renewed calls to abolish the Senate filibuster.
