Gail Coniglio, 52, a Delray Beach Republican, stood in the crowd wearing pins for Mr. DeSantis and Mr. Scott.
“This isn’t just about Broward County: This is about voter fraud nationwide,” she said. “We are showing government leaders we are not standing for this. It’s got to be investigated.”
Joe Duva, 67, of Tamarac, cited a court ruling from earlier this year that found that Dr. Snipes’s office had destroyed ballots from a 2016 congressional race.
“I heard a lot about corruption in blue Broward in 2016 when ballots were destroyed,” he said. “The responsibility goes to the top. Brenda Snipes dropped the ball here; it’s happened again.”
In Palm Beach County, where authorities were still reviewing provisional ballots, Ms. Bucher, the elections supervisor, said she was sensing attempted interference in the vote-counting process from senior elected officials, which she attributed to the political makeup of her county, where Democrats substantially outnumber Republicans.
“I just felt that it’s very unfortunate that some of the highest elected officials in our country are trying to disrupt our democracy because they don’t like the demographics of our voters,” she said. “I would wish they would allow us to continue to count the ballots.”
She said provisional election results would be completed by Friday afternoon.
Florida’s 67 counties must submit unofficial results to the state by noon on Saturday. At that point, Mr. Detzner, an appointee of Mr. Scott, must order machine recounts for races with a margin of 0.5 percentage points or less. Three statewide races currently fall under that threshold: the Senate race, in which Mr. Scott leads Mr. Nelson by 0.18 percentage points; the governor’s race, in which Ron DeSantis, a Republican, leads Andrew Gillum, a Democrat, by 0.44 percentage points; and the agriculture commissioner race, in which Nikki Fried, a Democrat, leads Matt Caldwell, a Republican, by 0.04 percentage points.
