When Miss Beadle announces that it is time to elect the new Class President, Mary Ingalls, Nellie Oleson and a boy named Elmer Dopkins end up being the candidates.
Poor Elmer lives with a kind and loving father who cares deeply for him but tries to shield him from every hurt in the world, while the older boys laugh at him behind his back and pick on him.
Of course, Nellie does her best to buy her votes, using candy and parties to 'sway' the electors in her favour. (With help from her mother!) Mary wants to fight fire with fire but that isn't so easily done and when she decides to resign her candidacy after hearing Elmer's reasons for continuing to run, Nellie doesn't have a prayer.
A good episode where the bullies don't win and are made to feel justifiably ashamed.
