Looking at the Florida Presidential Map per county, Trump ended up losing only 9 counties out of 67 total in the state, although the ones that he lost were by wide margins. I don't think Florida was cheated (at least not by the Republicans), but it was the most important swing state and the one that decided this election. The moment Trump officially won Florida, he had all the momentum, leading to him winning Ohio and North Carolina, as well as shocking everyone in Wisconsin, Michigan, and Pennsylvania.
I think that will take a few days and the protests will calm down. If the environment Trump will tell him to speak in normal speech without the outrageous, the passion subsides.
