Anthony quote, "No self-respecting woman should wish or work for the success of a party who ignores her sex," in front of the NWP headquarters in Washington in June 1920. “All men are created equal.” Few words in American history are invoked as often as the preamble to the Declaration of Independence, published nearly 250 years ago, and few more difficult to define.
