From The Origins of Progressive Agony by Victor Davis Hanson a the National Review:
Progressive astrologists predicted a series of Obamas for the next half-century. But in truth, the country was never really progressive. Until Obama, no Democrat without a Southern accent had won the popular vote since John Kennedy in 1960. And by 2010, the pushback became a near rout, within a few years, leaving the Left with its last vestige of power: a divided Supreme Court, which since the Roosevelt era had always salvaged the progressive dreams that had been wrecked in the executive and legislative branches.
When Democrats lost, they realized that they still lived in a Republic and not a volatile Athenian democracy — and found this also hard to take.
More exasperating still was the loss of the Supreme Court, the last bastion of elite brilliance and superior morality that might yet save America from the prejudices and ignorance of the irredeemables, deplorables, clingers, and crazies.
Having lost most state governments, both houses of Congress and the White House, The Supreme Court was their last line of defense. They defended it with desperation and conviction, but without any sense of honor.
