I wouldn't say so. Florida's Hispanics are less favourable to Clinton than national average while blacks voted almost unanimously for her.
The surging Hispanic vote definitely isn't voting for Trump. They were 60-40 for Obama in 2012 in Florida, maybe 70-30 at worst for her this year, which is still a huge improvement.
Remember also that much of the new Hispanic vote is either Puerto Ricans fleeing economic collapse on the Island, and if memory serves, Puerto Ricans vote Democratic at nearly the rate Blacks do. Also, young Cubans who would have aged into the voting pool or registered for the first time are much less Republican than their elders.
