S03E20: The Election

As a prank to make him look foolish, the older boys of Walnut Grove school nominate the object of their practical jokes, gentle Elmer Dobkins, to run for class president against popular Mary Ingalls and wealthy Nellie Oleson. While Mary and Nellie wage their campaigns with promises of popcorn and gum balls, Mr. Dobkins witnesses his son being teased by the older boys and, when he finds out why Elmer was nominated, angrily orders him to pull out of the election. But, when election day comes and the race seems too close to call, a cruel act and children tired of being bullied decide the outcome.
