WASHINGTON Senate Majority Leader Mitch McConnell (Ky.) and his fellow Republicans pulled the nuclear rules trigger Thursday, gutting the filibuster rule for Supreme Court nominees after Democrats blocked President Donald Trumps conservative pick, Neil Gorsuch.

Democrats argued that Gorsuch, a Colorado federal appeals court judge, was simply too conservative, and were nearly united in filibustering his nomination . They also criticized Republicans for the way they treated President Barack Obamas Supreme Court nominee, Merrick Garland, who was denied both a hearing and a vote last year.

That name is the reason we are in this spot today, Sen. Dick Durbin (D-Ill.) said of Garland. For the first time in the history of the Senate, for the first time ever, this Republican-led Senate refused to give this nominee a hearing and a vote. It had never, underline the word never, happened before.

Republicans said the other side was making history of their own by carrying out the first partisan filibuster of a Supreme Court nominee.

We need to restore the norms and traditions of the Senate and get past this unprecedented partisan filibuster, McConnell said, moments before rattling off procedural speak that set the rules change in motion.

It takes 60 votes to end a filibuster. Since there are 52 Republicans , and they could only come up with a few Democrats to join them in voting to end the filibuster, the only way McConnell could confirm Gorsuch was to change the rules by challenging that 60-vote standard, and then demanding a vote on it.

I raise a point of order that the vote on the cloture under the precedent set on 11/21/2013 is a majority vote on all nominations, he said.

Under the rules, the senator in the chair was obligated to rule that McConnells point was wrong, which then allowed him to appeal for a vote of his fellow senators to disagree with the ruling. All 52 Republicans voted to disagree. All 48 Democrats voted to uphold it.

That resulted in permanently changing the Senate rules so it only takes 51 votes to advance a Supreme Court nominee. Majority parties will no longer have to concern themselves, at all, with the opinions of the minority party or their voters for any presidential appointments.

It normally takes a two-thirds vote, or 67 votes, to jettison Senate rules in the middle of a session. The fact that McConnell used the nuclear option to do it is a rare step that generates extreme ill-will in a historically deliberative body.

After changing the rules, McConnell held the vote again on advancing Gorsuchs nomination. It passed, 55 to 45, under the new rules. All thats left now is Gorsuchs confirmation vote, which is set for Friday.
