Florida's primary elections are closed, meaning voters registered with a political party cast ballots for members of that party in advance of the November general election. Voters not registered with a party can cast ballots in nonpartisan races on the primary ballot, such as school board seats.

This year's primary ballots feature the gubernatorial races. The Democratic ballot comprises former U.S. Rep. Gwen Graham, former Miami Beach Mayor Philip Levine, Tallahassee Mayor Andrew Gillum and businessmen Jeff Green and Chris King. On the Republican side, Florida Agriculture Commissioner Adam Putnam and U.S. Rep. Ron DeSantis are vying for a spot in the Nov. 6 general election.

Also on Florida primary ballots are the all but uncontested races for the U.S. Senate seat currently held by Democrat Bill Nelson. Nelson does not have a primary challenger, and the Republican contender, Gov. Rick Scott, faces only token opposition from California businessman Roque "Rocky" De La Fuente.

Locally, primary ballots will include the 1st Congressional District seat held by Republican Matt Gaetz. Gaetz faces partisan opposition from Cris Dosev, a businessman and former Marine, and retired Navy pilot John Mills. The Democratic primary features Phil Ehr, a retired Navy officer, and Dr. Jennifer Zimmerman, a pediatrician in Santa Rosa County.

Other local primary races include county commission, school board and fire district contests. Mail-in voting already has begun, and as of this week almost 600,000 early votes had been cast statewide.

Looking ahead, Oct. 9 is the last day to register to vote in the Nov. 6 general election.
