Of Thee I Sing is a musical with a score by George Gershwin, lyrics by Ira Gershwin and a book by George S. Kaufman and Morrie Ryskind. The musical lampoons American politics; the story concerns John P. Wintergreen, who runs for President of the United States on the "love" platform. When he falls in love with the sensible Mary Turner instead of Diana Devereaux, the beautiful pageant winner selected for him, he gets into political hot water.
