<P> The executive power in the federal government is vested in the President of the United States , although power is often delegated to the Cabinet members and other officials . The president and vice president are elected as running mates by the Electoral College , for which each state , as well as the District of Columbia , is allocated a number of seats based on its representation ( or ostensible representation , in the case of D.C. ) in both houses of Congress . The president is limited to a maximum of two four - year terms . If the president has already served two years or more of a term to which some other person was elected , he or she may only serve one more additional four - year term . </P>
