Divided government in the United States

In the United States of America, divided government describes a situation in which one party controls the White House (executive branch), while another party controls one or both houses of the United States Congress (legislative branch). Divided government is seen by different groups as a benefit or as an undesirable product of the model of governance used in the U.S. political system. Under said model, known as the separation of powers, the state is divided into different branches.

Each branch has separate and independent powers and areas of responsibility so that the powers of one branch are not in conflict with the powers associated with the others. The degree to which the president of the United States has control of Congress often determines their political strength, such as the ability to pass sponsored legislation, ratify treaties, and have Cabinet members and judges approved. Early in the 19th century, divided government was rare. Since the 1970s it has become increasingly common.
