I haven't read anything by Asturias yet, but the impression I've gotten is that he's more well known for his later works, which are based around indigenous cultures and influences. He was part of a group of latino authors pioneering works regarding indigenous American cultures in this period. El Señor Presidente is one of his earlier works and falls outside of that category. Even looking at this book though, isn't this just an earlier predecessor to the the flood of Latin Boom works about dictators and politicians that would follow? In this sense, perhaps he was an influence on these later writers.
The thing with the bloom is that is not like a movement, with central figuere and ideas, but rather an arbitrary grouping of a heterogenous group of writers from different generations, countries and cultures that just happen to be latin american and write in spanish. Because of this, anyone writting before the 60's when the boom happened is a precussor, even if this really means nothing since the main trigger for the boom still the reckongntion of Borges's prose in Europe (and a bit behind, Neruda's poetry). So, yeah, Austurias is a precussor (to the magic realism too), but since the figure of Borges is so dominating and Borges was never a big fan of Asturias, he does not get advantage of this to be more published.
