There are exceptions, of course. Liberal Jewish New York teachers cluster at the south end of Palm Beach County and usually vote en bloc as liberal Democrats. Happily, Southwest Florida -- from Naples up to Sarasota -- is strongly Republican due to newcomers from the Midwest, along with many CIA, FBI, and military retirees from throughout the country.
The recent flow of Hispanic immigration to Florida has been dominated by poor and illegals from Mexico and Central America and threatens to turn Florida Blue. Yet even with Hispanics, there is cause for hope. Black identity politics does not sit well with them, and the aggressive Leftism of so many Democratic candidates is a major vulnerability with middle and upper class Hispanics -- especially with the recent influx from Venezuela.
There is also cause to be cheered by individual examples: a young Brazilian woman I know recently became a US citizen, pushing the process as much as she could because she wanted to vote for Donald Trump. She did so, with pride, and has also touted her recent vote for Bolsonaro for Brazilian president!
The last Florida governors election didn’t feel like GOP dominance to me. And I don’t think voter fraud explains all of it. Just sayin’.
