Really?  How old are you?  I have been to Puerto Rico numerous times and even hired people from Puerto Rico.  I am not an expert, but I do recall over the past few years that Puerto Ricans tried to assassinate President Truman, shot up the Congress and wounded a few Congressmen.  I recall those perpetrators being released and having a parade in the Puerto Rican neighborhood of NYC.  I recall them being hailed as heroes when they returned to P.R.  I also remember well that there have been three elections in Puerto Rico.   The people had a choice of becoming a state (This would have required them to pay federal taxes.  They never paid a cent.) or to vote Independence or to leave things as they are (Get all the free stuff and benefits from the U.S. just as if the whole island was on federal welfare.).  And you think we have ignored P.R.  Hell man, they drove out the Navy which provided Billions to their economy and thousands of jobs and we ignored them?  What a misinformed fool you are.
