Though the precedent regarding presidential succession due to the president's death was set, questions concerning presidential "inability" remained unanswered, such as what constituted an inability, who determined the existence of an inability, and did a vice president become president for the rest of the presidential term in the case of an inability or is the vice president merely "acting as president". Due to this lack of clarity, later vice presidents were hesitant to assert any role in cases of presidential inability.
