2. 'Playing games with the military'

WHAT: “McGovern Defense” 

WHEN: 1972

WHO: Sen. George McGovern (D) of South Dakota vs. President Richard M. Nixon (R)

BACKGROUND: Former Treasury Secretary John Connally created an organization called “Democrats for Nixon” to campaign against McGovern. This ad, coming with the Vietnam War still raging, focused on McGovern’s proposed cutbacks to military spending.
