[Article One, Platform of the States' Rights Democratic Party, 1948]
Prior to the election of Franklin D. Roosevelt, the Supreme Court had repeatedly torpedoed all attempts to pass federal legislation outlawing child labor, regulating working hours, establishing a minimum wage, protecting the right of workers to form labor unions, and so forth. These were all deemed to be "unconstitutional"!
Even after FDR's election, the Supreme Court continued to strike down many provisions of the New Deal on the same grounds. Finally, Roosevelt reminded the Court that the Constitution allowed him, in theory, to appoint as many Supreme Court Justices as he pleased. At first the Justices thought he was bluffing. But as the Judiciary Reorganization Act of 1937 (sometimes called Roosevelt's "court packing plan") began to work its way through Congress, suddenly the nation's highest court began to change its tune. Eventually that bill failed, but so did the attempted judicial activism of right-wing Justices opposed to the New Deal.
In 1948, President Harry Truman ordered the desegregation of the US military and established the President's Committee on Civil Rights. Worse still, in the eyes of some die-hard bigots, the 1948 Democratic Convention adopted a Civil Rights plank, at which point a number of southern Democrats walked out of the Convention. These southern Democrats soon announced the formation of a new party, the first plank of whose unanimously adopted platform states proudly: "We believe that the Constitution of the United States is the greatest charter of human liberty ever conceived by the mind of man."
But the Civil Rights movement continued to make progress, all the while being opposed by those who proclaimed their undying love for the Constitution. When the University of Alabama was ordered, by a federal judge, to allow black students to enroll, then Governor George Wallace delivered his famous "school house door" speech in support of segregation, in which he used the word "Constitution" 18 times.
After delivering that speech, George Wallace stood aside to allow Vivian Malone Jones and James Hood, accompanied by federal marshalls and Alabama National Guard troops, to enter Foster Auditorium and register as students.
