Did PR voted largely for Dems. historically?

[Clemenza]

Two main political parties in PR since the 1960s have been the PRD who are pro-commonwealth, and the PNP who are pro-statehood, with power going back and forth between the two over the years. PRD members are usually unaffiliated or Democrats. PNP members are generally affiliated secondarily with either the Dems or the GOP. I would say that in the PNP there are more Dems than Republicans, but all of the Republicans who are in PR affiliate with the GOP out of convenience.

Current governor of PR is a PNP member who is also a Democrat. PRD controls the commonwealth legislature.

Since PR was allowed to elect governors in the late 1940s, there have been two elected governors who were PNP and also affiliated with the GOP (Luis Ferre and Luis Fortuno). When the Democrat/PNP governor Ricky Rossello resigned under scandal a few years back, Wanda Vasquez was appointed governor, who was of the same party (PNP), but also affiliated with the GOP. PR politics are confusing for folks from the mainland and sadly very corrupt on all sides.
