God, Bless America?
Consider this reality: The omnipresence of "God bless America" as a political slogan is an entirely recent phenomenon. We know because we've run the numbers. Analysis of more than 15,000 public communications by political leaders from Franklin Roosevelt's election in 1932 — the beginning of the modern presidency — through six years of George W. Bush's administration revealed that prior to Ronald Reagan taking office in 1981, the phrase had passed a modern president's lips only once in a major address: Richard Nixon used it to conclude an April 30, 1973, speech about Watergate.
But Reagan brought "God bless America" into the mainstream by regularly using it to conclude his speeches. Since then, presidents and other politicians have used it nearly to death. Like Nike's "Just Do It" or any other ubiquitous catchphrase, the words eventually lose their meaning. "God bless America" has become the Pennsylvania Avenue equivalent to consumerized Madison Avenue staples.
