Political patronage is a dirty word to many. It is one of the principles of the American Idea that in this land of opportunity, we'll choose the best person for the job, no matter their political affiliation. For about a century after our modern Constitutional government was formed, patronage was the name of the game and each change in administration meant a massive civil service turnover, and of course, corrupt bargains and payoffs for positions.
The Feds fixed the issue in 1883 with the Pendleton Civil Service Reform Act. Puerto Rico had its own remedy, the Public Service Human Resources Administration Act of Puerto Pico, which espoused "merit principles" over patronage.
