This is something i only seen Manmademan talk about, but journalists are starting to pick up on. In the last 4 years about a million Puerto Ricans have moved to Florida. And because polls rarely do them in Spanish they might go unaccounted for until election day.About 1,000 Puerto Ricans families are relocating to Florida each month, according to the Puerto Rico Federal Affairs Administration. Osceola County, home to Orlando and Kissimmee, is more than 50 percent Latino, up from 45 percent in 2010, and many of those newcomers are Puerto Rican.
As U.S. citizens, Puerto Ricans are eligible to vote in the presidential election the minute they get to the U.S. This makes the greater Orlando area a target-rich environment for campaigners for both Clinton and Trump.
