Puerto Rico (and any territory, for that matter) isn’t allocated any votes in the Electoral College. That means that, although its residents are U.S. citizens and use the dollar as currency, they aren’t necessarily able to vote for president.

Comedian Tony Hinchcliffe called the U.S. territory a "floating island of garbage" at a Trump rally in Madison Square Garden.

The two parties that have dominated Puerto Rican politics for decades are losing their grip as they face the stiffest competition yet from a younger generation fed up with the island’s corruption, chronic power outages and mismanagement of public funds.
