Senate Republicans had to know there would be a price for their unprecedented theft of President Barack Obama’s final Supreme Court pick last year. On Thursday, Chuck Schumer, the Senate minority leader, named it: Either find 60 votes to overcome a filibuster of President Trump’s extremely conservative nominee, Judge Neil Gorsuch, or find another, more moderate choice. The last four Supreme Court nominees — two from Mr. Obama and two from President George W. Bush — all met the 60-vote threshold, Mr. Schumer said, so it was fair to require the same of Judge Gorsuch.
