The Florida Secretary of State website has this list of candidates for federal and state office for 2022. The list includes candidates who ran in the primary and lost, so it must be read carefully.
The Libertarian Party has nominees for Governor, U.S. Senator, and two U.S. House seats. The Green Party has two legislative nominees. The Constitution Party has one legislative nominee.
It appears that there are far fewer Libertarian Party candidates than in previous years.
