A sharp address given by Mayor Hubert Humphrey of Minneapolis—as well as the local political interests of a number of urban bosses—convinced the convention to adopt a stronger civil rights plank, which Truman approved wholeheartedly.[184] Truman delivered an aggressive acceptance speech attacking the 80th Congress, which Truman called the "Do Nothing Congress,"[147] and promising to win the election and "make these Republicans like it."[185]

Republicans approve of the American farmer, but they are willing to help him go broke. They stand four-square for the American home—but not for housing. They are strong for labor—but they are stronger for restricting labor's rights. They favor minimum wage—the smaller the minimum wage the better. They endorse educational opportunity for all—but they won't spend money for teachers or for schools. They think modern medical care and hospitals are fine—for people who can afford them ... They think American standard of living is a fine thing—so long as it doesn't spread to all the people.
