Christian conservatives, for more than two decades a pivotal force in American politics, are grappling with Election Day results that repudiated their influence and suggested that the cultural tide — especially on gay issues — has shifted against them.

They are reeling not only from the loss of the presidency, but from what many of them see as a rejection of their agenda. They lost fights against same-sex marriage in all four states where it was on the ballot, and saw anti-abortion-rights Senate candidates defeated and two states vote to legalize marijuana for recreational use.

It is not as though they did not put up a fight; they went all out as never before: The Rev. Billy Graham dropped any pretense of nonpartisanship and all but endorsed Mitt Romney for president. Roman Catholic bishops denounced President Obama’s policies as a threat to life, religious liberty and the traditional nuclear family. Ralph Reed’s Faith and Freedom Coalition distributed more voter guides in churches and contacted more homes by mail and phone than ever before.

“Millions of American evangelicals are absolutely shocked by not just the presidential election, but by the entire avalanche of results that came in,” R. Albert Mohler Jr., president of the Southern Baptist Theological Seminary, in Louisville, Ky., said in an interview. “It’s not that our message — we think abortion is wrong, we think same-sex marriage is wrong — didn’t get out. It did get out.

“It’s that the entire moral landscape has changed,” he said. “An increasingly secularized America understands our positions, and has rejected them…”

Compared to the rest of the industrial, educated world, that is long overdue.

The election results are just one indication of larger trends in American religion that Christian conservatives are still digesting, political analysts say. Americans who have no religious affiliation — pollsters call them the “nones” — are now about one-fifth of the population over all, according to a study released last month by the Pew Forum on Religion and Public Life.

The younger generation is even less religious: about one-third of Americans ages 18 to 22 say they are either atheists, agnostics or nothing in particular. Americans who are secular are far more likely to vote for liberal candidates and for same-sex marriage. Seventy percent of those who said they had no religion voted for Mr. Obama, according to exit polls conducted by Edison Research.

“This election signaled the last where a white Christian strategy is workable,” said Robert P. Jones, chief executive of the Public Religion Research Institute, a nonprofit, nonpartisan research and education organization based in Washington.

“Barack Obama’s coalition was less than 4 in 10 white Christian,” Dr. Jones said. “He made up for that with not only overwhelming support from the African-American and Latino community, but also with the support of the religiously unaffiliated.”

Nope. There is no tsunami of Reason in America. But, slowly, surely, as communications in your pocket and purse expand to include the whole world beyond network television – and mom and dad – the times they are a’changing. More like Darwin – than Dylan ever imagined.
