Information:  - Andrew Mark Cuomo (born December 6, 1957) is an American politician who has been the 56th Governor of New York since January 1, 2011. A member of the Democratic Party, he was elected in 2010, holding the same position his father, Mario Cuomo, held for three terms from 1983 to 1995.  - The Governor of the State of New York is the chief executive of the U.S. state of New York. The governor is the head of the executive branch of New York's state government and the commander-in-chief of the state's military and naval forces.  - A governor is, in most cases, a public official with the power to govern the executive branch of a non-sovereign or sub-national level of government, ranking under the head of state. In federations, "governor" may be the title of a politician who governs a constituent state and may be either appointed or elected. The power of the individual governor can vary dramatically between political systems, with some governors having only nominal and largely ceremonial power, while others having a complete control over the entire government.  - A commander-in-chief is the person or body that exercises supreme operational command and control of a nation's military forces or significant elements of those forces. In the latter case, the force element is those forces within a particular region, or associated by function. As a practical term; it refers to military competencies that reside in a nation-state's executive leadershipeither a head of state, a head of government, a minister of defence, a national cabinet, or some other collegial body. Often, a given country's commander-in-chief (if held by an official) need not be or have been a commissioned officer or even a veteran. This follows the principle of civilian control of the military.  - A head of state (or chief of state) is the public persona that officially represents the national unity and legitimacy of a sovereign state. In developing the current Constitution of France (1958), former French president Charles de Gaulle said the head of state should embody "the spirit of the nation" (""). In some countries, typically those with parliamentary governments, the head of state is a ceremonial figurehead that does not actually guide day-to-day government activities and may not even be empowered to exercise any kind of political authority (e.g., Queen Elizabeth II in the United Kingdom). In other countries, the head of state is also the head of government, such as in the U.S., where the president is both a public figurehead and the actual highest ranking political leader who, in practice, oversees the executive branch.  - A federation (also known as a federal state) is a political entity characterized by a union of partially self-governing states or regions under a central (federal) government. In a federation, the self-governing status of the component states, as well as the division of power between them and the central government, is typically constitutionally entrenched and may not be altered by a unilateral decision of either party, the states or the federal political body. Alternatively, federation is a form of government in which sovereign power is formally divided between a central authority and a number of constituent regions so that each region retains some degree of control over its internal affairs.  - Charles J.
