Pat Nixon was President Richard Nixon's wife and was the First Lady of the United States from 1969-1974. 

The "Pat for First Lady" message was popular during her husband's campaign against John F. Kennedy in the election of 1960. This slogan could be seen on buttons and bumper stickers, among other items. It was specifically targeted toward housewives, a group that the Republican Party courted during the 1950s. The media went so far as to try to create a race between Pat Nixon and Jacqueline Kennedy, whose husband would ultimately win the Presidency.
