In the United States, the title "Governor" refers to the chief executive of each state or insular territory. Governors retain sovereign police power, are not subordinate to the federal authorities except by laws provided by the enumerated powers section of the federal constitution, and serve as the political and ceremonial head of the state. Nearly three-fourths of the states (36) hold gubernatorial elections in the same years as midterm elections (2 years off set from presidential elections). Eleven states hold them in the same years as presidential elections (Vermont and New Hampshire hold elections every two years in every even numbered year), while the remaining five hold them in odd numbered years (two in the year after a presidential election, three in the year before).
