I thought that Bush v Gore was the worst Supreme Court ruling of my life.  I was misinformed:

The Supreme Court upheld President Trump’s ban on travel from several predominantly Muslim countries, delivering to the president on Tuesday a political victory and an endorsement of his power to control immigration at a time of political upheaval about the treatment of migrants at the Mexican border.

In a 5-to-4 vote, the court’s conservatives said that the president’s power to secure the country’s borders, delegated by Congress over decades of immigration lawmaking, was not undermined by Mr. Trump’s history of incendiary statements about the dangers he said Muslims pose to the United States.

Writing for the majority, Chief Justice John G. Roberts Jr. said that Mr. Trump had ample statutory authority to make national security judgments in the realm of immigration. And the chief justice rejected a constitutional challenge to Mr. Trump’s third executive order on the matter, issued in September as a proclamation.

The court’s liberals denounced the decision. In a passionate and searing dissent from the bench, Justice Sonia Sotomayor said the decision was no better than Korematsu v. United States, the 1944 decision that endorsed the detention of Japanese-Americans during World War II.

She praised the court for officially overturning Korematsu in its decision on Tuesday. But by upholding the travel ban, Justice Sotomayor said, the court “merely replaces one gravely wrong decision with another.”

Seriously.  This isn’t a difference in ideology, this is lack of basic humanity.
