In an effort to maximize the representation of African Americans and Hispanics in the United States House of Representatives, many state legislatures have consciously sought to create so-called “majority–minority” congressional districts. This involves carving out districts in which African Americans or Hispanics constitute more than 50 per cent of the voting age population. The expectation is that such districts will elect a minority member of the House, which in turn will lead to a Congress that is more sensitive and responsive to the needs and interests of America's two largest ethnic minorities. Indeed, this expectation has become an article of faith for the mainstream civil rights movement and its white sympathizers.

However, like other forms of affirmative action, majority–minority districting sits rather uncomfortably alongside the Constitutional principle of race-neutrality. In a series of recent cases, the United States Supreme Court has declared that, by subordinating traditional districting principles to the overriding need to draw boundaries along racial lines, states have violated the Equal Protection clause of the Fourteenth Amendment.
