PPD candidate Delgado is mayor of the northern coastal town of Isabela. His party has historically been an ally of the mainland Democratic Party and a supporter of the island's current Commonwealth status. The PPD's leadership, however, has veered toward supporting independence (which they euphemistically call "sovereignty", which Delgado himself supports). It has also been reported that Delgado doesn't know English.
Governor Vázquez, a Republican and Trump supporter who was opposed by the Growing Economic Opportunities PAC, lost the PNP gubernatorial primary to Pierluisi, a Democrat, earlier this year. While the PNP has Republican and Democrat members and supports statehood for Puerto Rico, the GOP has been, historically, the driving force behind the statehood movement, of which the island's Democrats are relative newcomers. Former Governor Rosselló is also a Democrat.

Coordination laws should be unconstitutional because they are unenforceable and they are all coordinating anyway.
That’s exactly how they defeated the good GOP governor they had about 10 or so years ago, I was in PR for about a week just a couple of days before the election and the hotel staff was terrified that the Dem would win because of all the union money. And he did.
The GOP governor had promoted private businesses, the tourism industry, better education, and all the things the Dem Marxist municipal unions hate. The SEIU was the big dog there.
