The Democratic primary for governor features a diverse slate of five candidates, including Philip Levine, a former Miami Beach mayor; Gwen Graham, a former United States representative; and Andrew Gillum, the mayor of Tallahassee.

Governor candidates on the Republican side have highlighted their loyalty to President Trump, who has endorsed Representative Ron DeSantis, over his chief rival, Adam Putnam, the state’s agriculture commissioner.

A House seat in the 27th Congressional District is up for grabs, thanks to the retirement of Representative Ileana Ros-Lehtinen, a Republican. Five Democrats are vying to replace her — Donna Shalala, the former president of the University of Miami and a former Clinton administration official, is leading the pack.

Nearby, in the 26th District, the incumbent, Carlos Curbelo, a Republican, may face a challenge holding onto the seat. On the Democratic side, Demetries Grimes and Debbie Mucarsel-Powell will compete for the chance to unseat Mr. Curbelo in November.
