The head of the executive branch in all 50 states and five commonwealths of the United States is known as a governor. The range of powers that each governor exerts over her state varies, depending on the distribution of power in the constitution of that particular state.
One of the universal powers governors wield is the ability to veto legislation. The qualifications to become the governor of a state vary with respect to each state or commonwealth. Some states require a governor to be at least 35 years of age, while other states have no age requirement. Every state and commonwealth has a four-year term for governors, except New Hampshire and Vermont, where the term is two years.
