I understand we all want Trump to go down like the Titanic, but you are wrong. Puerto Ricans are under 4% of Miami. They are not going to change a vote, and they do not vote as a group.
The Cuban vote is changing. Again, the days of the blind faith to the GOP is ending. Or could end with a better policy towards Cuba. So they do not vote as a group.
South Americans are not a huge population group. Central Americans, yes. All my Central American friends living in Miami split their votes. Their kids vote Dem. And why did you single out Pinochet?
Haitians vote as a block, led by perception of how they are treated in the US, how the US treats Haiti, and a lot by their churches. They were not kind to Hillary due to her and Bills actions in Haiti. Fuckers maintain a long memory as well.
Add in the Snowbirds (usually from the NE and older). Not sure if they split the vote or all go with what Marge says at the latest Canasta event at Del Boca Vista (There ya go YGIFS)
That leaves us with the White block from the rest of Florida. Do I need to say more?
Florida can change. And will be the Hispanic vote that does it as they move out of Miami, have more kids, and tend to not think rastlin gators is a good thing.
