Finally, there are many organizations that endorse gun prohibition but are not primarily concerned with the gun issue. For example, Common Cause is probably best known for its efforts to reform campaign financing. However, in a 1972 statement presented to a House Judiciary Subcommittee, the organization endorsed a "total ban on the sale and manufacture of all handguns" as well as a proposal that "private ownership of handguns also be prohibited." Likewise the U.S. Conference of Mayors, the Unitarian Universalist Association, the American Civil Liberties Union, Americans for Democratic Action, the National Alliance for Safer Cities, the National Board of the Young Women's Christian Association of the U.S.A., and the International Ladies Garment Workers' Union have all at some time endorsed banning the private possession of handguns. 37
