The state constitution of 1912 called for the election of a governor every two years. The term was increased to four years by a 1968 amendment. The constitution originally included no term limit, but an amendment passed in 1992 allows governors to succeed themselves only once; before this, four governors were elected more than twice in a row. Gubernatorial terms begin on the first Monday in the January following the election. Governors who have served the two term limit can run again after four years out of office.
