On March 16, Brian P. Moore filed in the Green Party primary to run for Governor of Florida. His Lieutenant Governor running mate is Jennifer Sullivan.

The Green Party has been ballot-qualified in Florida for 22 years, but never before has it had any statewide nominees (except president). This is largely because the filing fees are so high. The gubernatorial filing fee for a party member is $8,050.86.

Moore was the Socialist Party presidential nominee in 2008.

No left-leaning minor party has been on the ballot for Governor of Florida since 1920, when the Socialist Party ran F. C. Whitaker. He received 2.13% of the vote. The Communist Party, the Socialist Workers Party, the Party for Socialism and Liberation, the Peace & Freedom Party, and the Justice Party, have been on the Florida ballot in the past or currently, but none of them has ever run for Governor of Florida.
