Puerto Rico, like all the other US Territories, has a very limited participation in the process to elect the President. Both major parties have given Puerto Rico some delegates at their national convention. This book concentrates on the experience Puerto Rico has had on the nominating processes of both parties, particularly since 1980, when it began having presidential primaries. Unfortunately, once the primary season ends, Puerto Rico, like the rest of the territories, go back to be totally ignored by the presidential candidates. That's because the American citizens who live in Puerto Rico and the territories don't count at all in the general election. This unfair situation must change. The solution for this problem, in the case of Puerto Rico, is full admission into the union as a state. Puerto Rico has already voted twice in favor of becoming a state, in 2012 and 2017. It's time for Congress to act and grant the US citizens the political equality they have voted for.

Published in 1924 and widely acknowledged as a major work of twentieth-century Latin American literature, José Eustasio Rivera's The Vortex follows the harrowing adventures of the young poet Arturo Cova and his lover Alicia as they flee Bogotá and head into the wild and woolly backcountry of Colombia. After being separated from Alicia, Arturo leaves the high plains for the jungle, where he witnesses firsthand the horrid conditions of those forced or tricked into tapping rubber trees. A story populated by con men, rubber barons, and the unrelenting landscape, The Vortex is both a denunciation of the sensational human-rights abuses that took place during the Amazonian rubber boom and one of the most famous renderings of the natural environment in Latin American literary history.
