A general election was held in the U.S. state of Florida on November 6, 2018. All of Florida's executive officers were up for election as well as Florida's Class I Senate seat and all 27 seats in the United States House of Representatives. Primary elections were on August 28, 2018. The Republicans took control of the U.S. Senate seat held by three-term Democrat Bill Nelson in an upset, while the Democrats picked up two House seats as well as the office of the Commissioner of Agriculture. The Republican gains in the state, despite the trend towards Democrats nationwide, were part of Florida's transition from a swing state to a red state. As of 2025, the Agriculture Commissioner race was the last time Democrats won a statewide race in Florida, and also the last time a Democrat was elected to a state agriculture commissioner position in the US.
Senator Bill Nelson (D) ran for a fourth term against Governor Rick Scott (R). This ended up being the most expensive Senate race in U.S. history. Nelson was narrowly defeated by then-Governor Rick Scott.
Nelson was the only statewide Democrat to carry Monroe County.
Florida elects 27 U.S. Representatives from its congressional districts. Democrat Donna Shalala defeated Maria Elvira Salazar to succeed retiring Republican congresswoman Ileana Ros-Lehtinen in the 27th District and Debbie Mucarsel-Powell defeated incumbent Republican congressman Carlos Curbelo in the 26th District. This changed Florida's congressional delegation from a 16âÂÂ11 Republican majority to a narrow 14âÂÂ13 majority.
