“Trump has basically done more than any president has done in a single term since (President Jimmy) Carter to put his stamp on the judiciary,” said Jonathan Adler, a law professor at Case Western Reserve University School of Law in Cleveland. Congress created about 150 new judgeships during Carter’s presidency, he said. The impact will be enduring. Among the Trump-appointed judges, who hold lifetime positions, several are still in their 30s. The three Supreme Court picks could still be on the court at the 21st century’s midpoint, 30 years from now. Beyond the Supreme Court, 30% of the judges on the nation’s court of appeals, where all but a handful of cases reach their end, were appointed by Trump.
