A president must exercise wise decision making, which is simply the thought process of selecting a logical choice from the available options. Presidential decision making is a complicated process because presidents must seek to balance the needs of their national supporters, their party supporters and the general public. When making a decision, the president must consider the national constituency, or the group of voters the president represents. Since the president represents our entire country, he or she must act within the national interest, or the best interests of the nation. The president must also balance the needs of his or her partisan constituency, or the members of the president's political party. The president serves as the head of his/her political party and needs the support of party legislators in order to enact proposed legislation.
