The above link is for a brief bio on the winner of Mexico's 1940 election along with a history of his administration.
I Googled "List of Mexican Presidents" and when on the site, I just clicked on the name of the president for the years 1940-1946. I am going to click on each name after his administration to get the story of what happened in Mexico politically since then.
