Central Mexico City in 1940. (From National Geographic, October, 1940 issue) Mexico was torn politically during this time; the fascist candidate had garnered 40% of the vote in the popular election for president in summer, 1940. Riots broke out during the voting and claims of voter fraud followed the election. As Cash chronicled in his last unpublished piece, "Report From Mexico", it was difficult to determine just what the political make-up of the country was in this mercurial period in its history--the official end year of the thirty year long Mexican revolution begun in 1910. Mexico had sold oil to the Nazi Reich in 1938-39 until a British blockade after the invasion of Poland cut it off.
