In fact, leaders who courageously resisted the temptation of major federal initiatives at times of crisis presided over shorter, less painful recessions, while the ambitious innovations of Hoover and FDR worsened and prolonged the Great Depression. (Even liberal historians admit that the New Deal never worked as "a recovery program.")

Meanwhile, the popular assumption that our founders determined to create a secular, not a Christian, nation (Big Lie No. 3) has produced widespread hysteria over the program of "the Christian right."

In fact, the constitutional framers insisted on a combination of a secular government and a deeply Christian society. Even Jefferson, an unconventional religious thinker, believed that fervent faith represented a necessary element in the security and growth of the republic; he personally attended and authorized weekly Christian services in the Capitol building itself.

Secular militants, not Christian conservatives, currently strive to transform America in a way our founders would neither recognize nor approve.

Unfortunately, some of the same religious conservatives who get it right about the place of organized faith in the American fabric get it terribly wrong by signing on to Big Lie No. 10: that the United States has entered into a steep — and irreversible — moral decline.

In fact, a wealth of statistics concerning marriage, teenage sexuality, drug addiction, crime, alcohol abuse and other signs of social breakdown show a recent, decisive turnaround that may represent one of the nation's periodic "awakenings." Moralists have proclaimed permanent ethical collapse ever since 1645, yet no one could claim that our path has been straight downhill for 350 years.

The big lies about America all work to undermine the sense of honor and gratitude that ought to inspire every citizen, particularly in this Thanksgiving season. They also destroy the essential sense of perspective required in significant debates as a new government comes to power in Washington, D.C.

While Sen. Obama's supporters rightly rejoice at his election to the nation's highest office, they will disorient his presidency and damage society if they embrace destructive distortions about our past, and view his elevation as a rare (or exclusive) basis for pride.
