This award-winning documentary on DVD, produced by director Robert Drew in 1960, follows a week in the life of John F. Kennedy during the climax of his Wisconsin presidential primary run against Hubert Humphrey. The free wheeling photography captures the characters and flavor of campaign politics as they had never before been seen on film. John F. Kennedy's rational, charismatic presence, the squealing urban crowds, Jackie Kennedy's radiance, Bobby Kennedy's shy charm on the stump for his brother; Hubert Humphrey's down home populist appeal to farmers, his humor and affection for his wife, Muriel; the anxiety and contrasting styles of the two candidates as they anticipated the returns.

"Primary" is a cinematic experience unique in the history of film, the first in the development of American cinéma vérité, and a template for ground-breaking films Robert Drew would later shoot in the Kennedy White House.
