Even were the public still in the mood for fiery invective about family values, the G.O.P. has long since lost any authority to lead the charge. The current Democratic president and his family are exemplars of precisely the Eisenhower-era squareness  albeit refurbished by feminism  that the Republicans often preached but rarely practiced. Obama actually walks the walk. As the former Bush speechwriter David Frum recently wrote, the new president is an “apparently devoted husband and father” whose worst vice is “an occasional cigarette.”

Frum was contrasting Obama to his own party’s star attraction, Rush Limbaugh, whose “history of drug dependency” and “tangled marital history” make him “a walking stereotype of self-indulgence.” Indeed, the two top candidates for leader of the post-Bush G.O.P, Rush and Newt, have six marriages between them. The party that once declared war on unmarried welfare moms, homosexual “recruiters” and Bill Clinton’s private life has been rebranded by Mark Foley, Larry Craig, David Vitter and the irrepressible Palins. Even before the economy tanked, Americans had more faith in medical researchers using discarded embryos to battle Parkinson’s and Alzheimer’s than in Washington politicians making ad hoc medical decisions for Terri Schiavo.

What’s been revealing about watching conservatives debate their fate since their Election Day Waterloo is how, the occasional Frum excepted, so many of them don’t want to confront the obsolescence of culture wars as a political crutch. They’d rather, like Cantor, just change the subject  much as they avoid talking about Bush and avoid reckoning with the doomed demographics of the G.O.P.’s old white male base. To recognize all these failings would be to confront why a once-national party can now be tucked into the Bible Belt.

The religious right is even more in denial than the Republicans. When Obama nominated Kathleen Sebelius, the Roman Catholic Kansas governor who supports abortion rights, as his secretary of health and human services, Tony Perkins, the leader of the Family Research Council, became nearly as apoplectic as the other Tony Perkins playing Norman Bates. “If Republicans won’t take a stand now, when will they?” the godly Perkins thundered online. But Congressional Republicans ignored him, sending out (at most) tepid press releases of complaint, much as they did in response to Obama’s stem-cell order. The two antiabortion Kansas Republicans in the Senate, Sam Brownback and Pat Roberts, both endorsed Sebelius.

Perkins is now praying that economic failure will be a stimulus for his family-values business. “As the economy goes downward,” he has theorized, “I think people are going to be driven to religion.” Wrong again. The latest American Religious Identification Survey, published last week, found that most faiths have lost ground since 1990 and that the fastest-growing religious choice is “None,” up from 8 percent to 15 percent (which makes it larger than all denominations except Roman Catholics and Baptists). Another highly regarded poll, the General Social Survey, had an even more startling finding in its preliminary 2008 data released this month: Twice as many Americans have a “great deal” of confidence in the scientific community as do in organized religion. How the almighty has fallen: organized religion is in a dead heat with banks and financial institutions on the confidence scale.

This, too, is a replay of the Great Depression. “One might have expected that in such a crisis great numbers of these people would have turned to the consolations of and inspirations of religion,” wrote Frederick Lewis Allen in “Since Yesterday,” his history of the 1930s published in 1940. But that did not happen: “The long slow retreat of the churches into less and less significance in the life of the country, and even in the lives of the majority of their members, continued almost unabated.”
