When you wrote President Camacho I am sure you meant President Lázaro Cárdenas instead. Both Cárdenas and his predecessor Plutarco Elías Calles were interesting figures. Calles is even thought by some to be the author of "The Treasure of the Sierra Madre". Calles was a former bartender in Los Angeles before returning to Mexico after the revolution, and when his term as president ended, he had believed that Cárdenas would be a safe choice as his successor, a weakling that he could push around to preserve his influence. He was wrong: at the first whiff of a plot against him Cárdenas had Calles rounded up in the middle of the night and dumped across the border, back from where he came. It was reported that Calles was astonished that he survived, and was not shot out of hand, as he would have had done were the situation reversed.
