A crowded field and recent polling have kept the Florida 9th Congressional District Republican primary tight ahead of the August 18 vote. A Victory Insights survey from early August showed Jorge Martinez, Thomas Chalifoux, and Ben Butler statistically tied near 14 percent each, with Dan Green close behind at 12 percent and 41 percent of likely Republican primary voters undecided. Shared priorities on affordability, cost-of-living reductions, and border security have limited differentiation among the top contenders. An August 12 endorsement from Rep. Anna Paulina Luna lifted Green in prediction markets, though the frontrunners remain closely bunched. High undecided share and limited name recognition create room for late shifts before primary day.
