Replication Data for: The Domestic Politics of U.S. Treaty Ratification: Bilateral Treaties from 1949-2012

Treaties represent an important policy mechanism in U.S. foreign policy. There are good reasons to expect that the political process underlying treaty ratification in the U.S. is structured by the partisan political context, the policy context including the policy agenda, and, in the case of bilateral agreements, the relationship between the treaty partners. I analyze the duration of the ratification process for all bilateral treaties transmitted by the president to the Senate from 1949 to 2012. I focus the analysis on two key stages where delay is most common: the presidential transmittal stage and the Senate Foreign Relations committee stage. Analysis indicates that presidential resources, partisan polarization, the broader policy agenda, and the value of the treaty structure presidential decisions on treaty transmittal. I find less support for these factors at the committee stage; however, the committee processes treaties with democracies more quickly than treaties with other states. The results have important implications for U.S. foreign policy and help explain why recent presidents have largely avoided using formal Article II treaties to complete bilateral agreements.
