Divided government

A divided government is a type of government in which one party controls the executive branch while another party controls one or both houses of the legislative branch. The situation occurs in governance systems that follow the separation of powers model. Under said model, 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 typical division creates an executive branch that executes and enforces the law as led by a head of state, typically a president; a legislative branch that enacts, amends, or repeals laws as led by a unicameral or bicameral legislature; and a judiciary branch that interprets and applies the law as led by a supreme court.

Divided governments are seen by different groups as a benefit or as an undesirable product of said separations. Those in favor of divided government believe that the separations encourage more policing of those in power by the opposition, as well as limiting spending and the expansion of undesirable laws.[1] Opponents, however, argue that divided governments become lethargic, leading to many gridlocks. In the late 1980s, Terry M. Moe, a professor of political science at Stanford University, examined the issue.[2] He concluded that divided governments lead to compromise which can be seen as beneficial. But he also noticed that divided governments subvert performance and politicize the decisions of executive agencies.

The situation is common in developed nations but rare in developing ones. Early in the 20th century, for example, divided government was rare in the United States, but since the 1970s it has become increasingly common.

Divided governments are contrasted by government trifectas—a different situation in which the same party controls both the executive and legislative branches.
