I just recently started watching Narcos, which examines the Medellin Cartel and its infamous founder, Pablo Escobar. Escobar became the "King of Cocaine", making $60 million a day from cocaine sales at one time. He was also exceedingly popular with the Colombian people, many of whom were impoverished and viewed Pablo as a kind of Robin Hood. in 1982, he was elected as a Congressman in the Colombian Chamber of Representatives, and had dreams of becoming President. Evidently, he was unable to do this, and was ultimately shot and killed at the age of 44 by Colombian National Police after escaping from his own luxury prison.
Your challenge is to change Pablo Escobar's fate, and make him President of Colombia at some point. How this happens is up to you, but try to keep it at least somewhat within the bounds of plausibility.
