The United Nations Convention on the Rights of the Child (UNCRC or CRC) is an international human rights treaty which recognizes that all children possess fundamental human rights. The United States government has not ratified the CRC, despite the fact that within the US, the children’s rights movement has continually advocated for CRC ratification. Their efforts remain unsuccessful, in part due to the existence of the parental rights movement, which has adopted an anti-CRC stance, by calling upon the American public and government to reject the Convention. This paper takes a closer look at two major organizations which play a role in advocating for or against CRC ratification in the US: the two organizations are the Campaign for US Ratification of the CRC and ParentalRights.org. The research will borrow concepts from Keck & Sikkink and Hertel on transnational human rights advocacy, and seek to apply their theory to a single-country setting, in order to comment upon the patterns of campaign emergence and interaction. Finally, as a conclusion to the work, recommendations will be given to the Campaign for US Ratification of the CRC on ways to render their pro-CRC advocacy more effective.
