The Economist
specifically, US politics
: a parliamentary procedure in the U.S. Senate by which the requirement of the affirmative votes of a supermajority of senators is changed to require only a simple majority to invoke cloture in order to stop a filibuster and allow a vote on a matter (such as a judicial nomination) to proceed
Since Republicans can't muster the 60 votes necessary to overcome this particular filibuster, they now want to use their authority over Senate procedures to abolish the maneuver itself, at least for judicial nominees. Exercising this "nuclear option," as it is known, would theoretically require the support of just a simple majority of senators, which Republican leaders say they are on the verge of solidifying. —Jonathan Cohn
