The third filibuster of such a measure underscored how the legislation is unlikely to move forward without a change in Senate rules.
WASHINGTON — Republicans on Wednesday blocked action for the third time this year on legislation to bolster voting rights, leaving Democrats few options to advance the bill outside of changing the Senate filibuster rule and passing it over G.O.P.
All 50 Democrats and independents supported bringing the Freedom to Vote Act to the floor, but all 50 Republicans voted against doing so, maintaining a stalemate over a proposal that Democrats say is needed to counter efforts in Republican-controlled states to impose new restrictions on voting in the aftermath of the 2020 elections.
Senator Mitch McConnell, Republican of Kentucky and the minority leader, assailed the proposal put forward by Democrats on Wednesday, which was a compromise version of a broader voting rights measure that Republicans had blocked twice before.
