Even though the Florida legislature doesn’t convene until January 9, 2018, Florida legislative committees are already working on 2018 bills. On October 11, SB 45 passed the Senate Ethics and Elections Committee. It says that elected state and local officials who want to run for federal office must first resign their state or local position. See this story. The bill is sponsored by Senator Travis Hutson (R-Elkton).
Such “resign-to-run” laws have generally been upheld by courts. They do not run afoul of the principle that states can’t add to the qualifications to run for federal office, because they don’t block anyone from running for Congress. But, they do force potential federal candidates to take an action that they would probably rather not do.
