The GOP is alive and well in Puerto Rico. The GOPPR is like the "Tea Party" of Puerto Rico, see
http://www.goppr.org/category/cont/party-leaders, and they are often both Republican and PNP. Former Governor Pedro Rosello was a Democrat and I also believe that even Carlos Romero Barcelo was indeed a Democrat. This Senator is not your grandma's PNP, he is a Republican (Republicano) PNP, a teabagger.
This party (GOPPR) is "guarded" by their "Grandfathers" or the old Conservative operatives responsible of supressing until submission the pro-Independence movement with their scare tactics. They worked closely with the local police force, FBI and CIA to "exterminate" anything resembling Socialism or Communism; the Puerto Rico pro-Independence movement, Labor Parties and Unions, Student Unions, even calling for the implementation of "English Only" policies in Puerto Rico even when the mayority of PNP affiliates want to be able to have both English and Spanish as national languages.
Being a member of the Partido "Republicano de Puerto Rico" is pretty much putting a sign on your forehead saying that you are a filthy "Tea Partier". Governor Fortuno is a registered Republican implementing "Shock Doctrine" economic policies and creating the ultimate police state in order to further decimate the local economy. Their target has always been diminishing the public opinion of the country and telling Puertorricans that they cannot make it on their own and that they must become part of the Union. So many decades of doing this is finally paying off as Puertorricans (locan and those living in the USA) are currently convinced that there is no way out of poverty without becoming a US State. He ephitomizes the utra-conservative sector of the PNP or ironically called "Partido Nuevo Progresista (New Progressive Party).
