In the presidential system, the executive power is vested in the president. There is total separation between the executive, that is, the president and the legislature. The president is elected directly by the people, as is the legislature. Neither the president nor any member of his or her cabinet can be a member of the legislature, and the terms of the president and of the legislature are fixed. The president cannot be removed by the legislature through a vote of no confidence (but may be removed for serious misconduct by a formal process known as impeachment), and the president cannot dissolve the legislature. The president appoints his ministers and senior administrators, although their appointment requires the approval of the legislature. Normally, all executive functions are vested in the president, and the role of the cabinet is merely to advise the president. The president and the majority of the legislature do not necessarily have to be from the same political party, and the president has far less control over the legislature than is usually the case in a parliamentary system. But since all laws, including the adoption of the budget, have to be passed by the legislature, the president has to work with the legislature to ensure that his or her policies and plans can be carried out.
