Florida Gov. Ron DeSantis is shaking things up with a bold move that could have major consequences for one very famous Floridian: Donald Trump. DeSantis is pushing for strict new rules on citizen-led ballot initiatives, a change that might slam the door on Trump’s hopes of opening a casino in Miami.

Here’s the deal: Florida’s constitution says any expansion of gambling needs voter approval through a ballot initiative. DeSantis’ plan would make it much harder for citizens to get these initiatives on the ballot. If it passes, it could leave Trump’s casino dreams stuck in the sand.

The governor’s proposal would overhaul how petitions are collected. Instead of gathering signatures in public, Floridians would have to request forms from their local election offices, making the process cumbersome. Even organizing petition drives could become a felony under the new rules. Critics say this would effectively kill the citizen initiative process.

DeSantis argues the changes are needed to stop “special interests” from buying their way onto the ballot. But opponents, like Democratic consultant Ben Pollara, call it a power grab that would stifle voters’ voices. “This just kills it,” Pollara said. “It’s not something you can spend your way out of.”

The Seminole Tribe of Florida, which already runs casinos and has exclusive rights to sports betting in the state, could benefit big time from DeSantis’ plan. A 2018 amendment requires voter approval for gambling expansion, and the new rules would make it nearly impossible for competitors like Trump to even get a shot.

Trump, who’s been eyeing a Miami casino for years, might face an uphill battle. His Doral resort, just outside the 15-mile radius of the Seminole-owned Hard Rock casino, seemed like a prime location. But without voter approval, his plans could go bust.

DeSantis and Trump have had a rocky relationship, but they’ve recently made peace. Still, this move could put them back at odds. As lawmakers head into a special session this week, all eyes are on whether DeSantis’ gamble will pay off—and what it means for Trump’s next big venture.

The stakes are high, and for now, it’s anyone’s game.
