Presidential prestige or popularity has often been cited as an important source of presidential influence in Congress. It has not been empirically and systematically demonstrated, however, that such a relationship exists. This study examines a variety of relationships between presidential prestige and presidential support in the U.S. House of Representatives. The relationships between overall national presidential popularity on the one hand and overall, domestic, and foreign policy presidential support in the House as a whole and among various groups of congressmen on the other are generally weak. Consistently strong relationships
arefound between presidential prestige among Democratic party identifiers and presidential support among Democratic congressmen. Similar relationships are found between presidential prestige among the more partisan Republican party identifiers and the presidential support by Republican congressmen. Explanations for these findings are presented, and the findings are related to broader questions of American politics.
