In just the past week, the casualty count of Democratic priorities doomed by the filibuster has mounted; both police and immigration reform now appear to be blocked in the Senate, and legislation codifying abortion rights faces equally dim prospects. Simultaneously, the party has tied itself in knots attempting to squeeze its economic agenda into a single, sprawling “reconciliation” bill, because that process offers the only protection against a GOP filibuster. Meanwhile, legislation establishing a new federal floor for voting rights, the party’s top priority after the reconciliation bill, remains stalled in the Senate under threat of another GOP filibuster. And then, this week, Senate Republican Leader Mitch McConnell raised the temperature even higher by leading a Republican filibuster that has blocked Democratic efforts to raise the nation’s debt ceiling.
