Loyal Allies or Stubborn Establishment?

Abstract

AbstractTo what extent was U.S. President Donald J. Trump’s populist foreign policy agenda supported by the Republican Party (GOP) in Congress? A bourgeoning literature on Congress and U.S. foreign policy has identified increasing partisan disagreement on international issues. Trump’s “America First” policy may have further incited division and ideological controversies. At the same time, the 45th U.S. president’s foreign and security policies were, to a large degree, at odds with traditional GOP policy positions. To understand executive–legislative relations on foreign and security policy during the Trump administration, and in particular the role of the GOP, this paper first investigates voting records in Congress during the Obama and Trump presidencies. The analysis reveals that the reaction to Trump’s “America First” doctrine was not uniform and that parts of the GOP asserted themselves against the president. To explain the sources of this variance, the article focuses on two policy areas with varied GOP positioning: arms control (pro Trump) and foreign aid (contra Trump). In sum, the analysis reveals that some Republicans with traditionalist views (the so-called GOP establishment) opposed some of Trump’s anti-internationalist policies, in particular those that contradicted long-standing GOP preferences regarding vital U.S. security interests. At the same time, Republicans supported Trump on issues where the GOP could continue its policy preference, on arms control in particular.
