Recent research on congressional-executive relations has concluded that partisan and ideological forces explaining decision making in domestic policy have also become dominant in the realm of foreign policy. Accordingly, scholars have inferred the effective demise of the two-presidencies. In this analysis, the authors compare models explaining bipartisan congressional support of the president on domestic issues with that of foreign and defense. Although factors relating to the congressional context tended to be influential in both policy areas, they found important differences in the effects of factors relating to the international context. They also found that congressional bipartisan support was significantly less likely on matters related to the purse strings and on issues such as trade. The contrasting effects of the explanatory factors across policy areas suggest the importance of both the two-presidencies and resurgent Congress perspectives in explaining congressional-executive interactions.
