The Governor is the Chief Executive Officer of the state. He is not a member of the Cabinet but the Governor and the Cabinet together are responsible for the management of several agencies and together make up several boards. The Governor sees that the laws of the state are carried out, he is commander-in-chief of all military forces of the state not on active duty of the federal government (for example the National Guard); he makes appointments to several hundred boards; he fills vacancies in state and county offices until elections are held; he submits an annual budget to the Legislature; and he makes proposals for legislation. The Governor also has veto power over acts passed by the Legislature.
    To be elected Governor, a person must be at least 30 years old and must have lived in Florida for at least 7 years. A person must also be a U.S. citizen, registered to vote, and cannot have been convicted of a felony unless their civil rights have been restored. There is no requirement that a candidate have any experience in government although many of Florida's past governors have been legislators.
    Prior to the 1968 revision of the Florida Constitution, the Governor was not allowed to run for re-election. Now he can serve two successive four-year terms.
