There was high drama Thursday on the floor of the Senate as Democrats significantly changed the way business in the chamber is done.
In what Republicans cast as a "power grab" but Democrats defended as a way to break gridlock, the Senate's rules were changed to make it much more difficult for a minority of the members to hold up action on key presidential nominees.
The political class was aflame Thursday with outrage (Republicans) and triumph (Democrats) as Senate Democrats voted to hem in the minority party's ability to filibuster most presidential nominees.
By a 52-48 vote, the Democratic-controlled Senate carried out the so-called nuclear option. The leadership will now allow a simple majority of senators to override filibusters on nominations, with the exception of those to the Supreme Court.
Previous precedent, in place since the 1970s, required a 60-vote "supermajority" to end a filibuster.
Yesterday, Republican Senator Rand Paul, of Kentucky, filibustered the Senate floor for nearly 13 hours in protest of the administration's use of drones.
SENATOR RAND PAUL: This is not about partisanship. I have allowed the president to pick his political appointees, but I will not sit quietly and let him shred the Constitution. I cannot sit at my desk quietly and let the president say that he will kill Americans on American soil who are not actively attacking a country.
