By 1919, Congress had approved the 19th Amendment to the Constitution, granting women the right to vote, and in 1920 it became law. Robinson felt the best way to prevent these newly franchised voters from being intimidated or influenced by the actions and rhetoric of Congress was through a publication that presented opposing views on controversial national questions. That way, if a woman "became enthused about some new Federal proposal, she could consult the opposite page and soon find out its shortcomings."

Today, Congressional Digest Corp. (CDC) continues that tradition under the direction of Page Robinson Thomas (Robinson's granddaughter) and her husband, R. Griffith Thomas. CDC's main publishing division is Pro & Con Publishers, covering Congress, the Supreme Court, the United Nations and other international tribunals.
