A Republican challenger is accusing Sarasota County Commissioner Joe Neunder of being bankrolled by the same developers building thousands of homes in Lakewood Ranch. Jim DeNiro released an AI-generated attack ad on Monday, July 27, that targets Neunder's record on growth, spending, and a 2016 donation to Hillary Clinton ahead of the Tuesday, August 18 primary.

DeNiro, a retired Sarasota Police Department sergeant with 30 years of service, released the one-minute video titled "Once Upon a Lie: The Story of Joe Neunder's Make-Believe Kingdom." The ad uses AI-generated imagery to depict Neunder walking through a fairy-tale forest, encountering a magic mirror, and standing over a desk covered in cash, according to Florida Politics.

The ad hits Neunder on three points: a $2,700 donation he made to the Hillary Victory Fund in September 2016, developer contributions to political committees supporting his re-election, and his vote for Sarasota County's $2.52 billion fiscal year 2026 budget, which the ad calls the largest in county history.

Developer donors have a Lakewood Ranch footprint

Among the developers the ad names is Pat Neal, president of Neal Communities, which is headquartered in Lakewood Ranch. Neal, who appeared on Forbes' billionaire list in March 2026, filed plans in May for Saltgrass, a 499-unit project that is the first phase of a 1,000-unit, 906-acre development in Lakewood Ranch. A separate 300-home Fieldstone project was proposed in April 2026.

The political committee Conservatives for a Brighter Future, which has promoted Neunder, received contributions from Neal along with developers Randy Benderson, Hugh Culverhouse, and Rex Jensen, Florida Politics reported.

"Joe Neunder's political fairy tale requires voters to forget that he financially supported Hillary Clinton, ignore the developers financing his political operation, and believe that a so-called fiscal conservative can vote for the largest budget in Sarasota County history," DeNiro campaign spokesperson Max Goodman said.

A separate committee, Take Back Sarasota, chaired by Siesta Key businessman Dave Balot, paid for mailers saying Neunder "stands up to developers." That committee's first reported contribution was $25,000 from SKRS MGMT LLC, a company tied to Balot and developer Michael Holderness.

Neunder's record on growth

Neunder, elected to the commission in 2022 after serving on the Venice City Council, has campaigned as a fiscal conservative and controlled-growth voice. On Friday, July 10, the commission voted to block hyperscale data centers for at least one year. "For me, it's a no … Not now, not ever," Neunder said at the Friday, July 10 commission meeting when the board voted to impose the moratorium.

On Tuesday, June 2, the commission approved a mobility fee reimbursement agreement with Neal Communities for a traffic signal at SR 776 and Old Englewood Road. The vote was 5-0, according to the county's action agenda.

The Neunder campaign did not respond to requests for comment on the ad.
