Regardless of how a measure makes it to the ballot, all amendments require a 60 percent voting majority to pass.
An amendment may be proposed by a two-thirds vote of both Houses of Congress, or, if two-thirds of the States request one, by a convention called for that purpose. The amendment must then be ratified by three-fourths of the State legislatures, or three-fourths of conventions called in each State for ratification.
Citizens may propose amendments to the Florida Constitution through an initiative petition process. In addition to other requirements, this initiative petition process requires a specific number of petitions to be signed by registered Florida voters before the proposed amendment by initiative can appear on the ballot.
