A Gubernatorial Election is the election for the Chief Executive of a State, better known as a Governor.
Each State decides how often to elect a Governor and by what rules they want to elect but the typical term is four-years with a two term limit, similar to the US President.
The maximum amount of time is 10 years. Two terms of five years.
