I'm not sure if this has been discussed yet, but apparently the city of Miami passed a resolution that favors the secession of South Florida.
I wouldn't be surprised. Since the territory of Florida was stolen from Spain, it's quite understandable that people of Florida want to stay away from their kidnappers! I know that you may say that it was too long ago for people to remember. But as a respond you may just have a look at the percentage of the secession moods among the states, that joined the Union by annexing the territory from the Spanish!!
