Florida filing for state office closed on June 20. In the 13th State House district, only one candidate, the incumbent, Reggie Fullwood, attempted to file. Because his Financial Disclosure statement is not properly notarized, the filing is defective. See this story.
Florida requires declared write-in candidates to file on the same day that candidates qualify for the primary and general election ballot, so it is too late for anyone to file as a write-in. Therefore, Florida will be required to hold a special election to fill the seat for the 2015-2016 legislative session. The district is in Jacksonville. Fullwood is a Democrat. Thanks to Austin Cassidy for the link.
