McCain, Obama briefly share the stage — and a hug

LAKE FOREST, Calif. — Sens. John McCain and Barack Obama shared the stage for only 36 seconds on Saturday, but in separate interviews gave a preview of the fall debates, offering sharply contrasting responses on social issues and personal worldviews.

On the stage at Saddleback Church, an evangelical megachurch here, they briefly hugged each other and smiled, belying a nastier campaign between them that has taken place long-distance and over the airwaves.

The hug was preceded by an hourlong interview with Obama and followed by an hourlong interview with McCain in the vast, warehouselike church before an attentive, enthusiastic audience of 2,200 people.

The men were interviewed by Rick Warren, one of the nation's most prominent evangelists and author of the best-selling book "The Purpose Driven Life."

Sitting at a table with Warren, each man spoke in often personal terms about their faith in Christ, confessed their moral failings, and tried to explain — or not explain — their thinking about such hot-button issues as abortion and gay marriage.

For Obama, the forum signaled a return to the campaign after a vacation in Hawaii and the start of a weeklong run-up to the Democratic National Convention, certain to include the announcement of his running mate.

For McCain, it also marked a ramping up after a low-key week.

For both, it was an opportunity to talk about their faith and the role it plays in public policy, a key pitch to religious voters who could be vital in a close election. They met as religious voters' loyalty to Republicans that hit a peak in 2004 may be waning, and Democrats may be making some inroads.

Among the points they made:

Their greatest moral failure

"The failure of my first marriage," said McCain. "It's my greatest moral failure."

Obama said he experimented with drugs and drank during a "difficult" youth when his father had left and he himself was overly selfish. "I couldn't focus on other people," he said.

Most gut-wrenching decision

McCain said it was when he refused early release from a North Vietnamese prison camp because it would have put him ahead of fellow American prisoners in violation of their code of conduct. "It took a lot of prayer," he said.

Obama said it was opposing the war in Iraq at a time it was politically risky and he believed that Saddam Hussein did mean to harm the United States. However, he said, he did not believe that Saddam had weapons of mass destruction.

On the meaning of their own Christianity

"It means I'm saved and forgiven," McCain said.

He told how his faith sustained him while he was a prisoner of war in Vietnam, recounting how one of his captors treated him humanely and once secretly drew a cross in the dirt to signal his own faith. "It was just two Christians worshipping together," he said.

"It means I believe that Jesus Christ died for my sins and that I am redeemed through him," said Obama. "That is a source of strength and sustenance. ... I know that I don't walk alone."

He said that influences his belief that people should think about helping the needy.

The three wisest people they would consult as president

McCain listed Gen. David Petraeus, the architect of the troop-increase strategy in Iraq; Rep. John Lewis, D-Ga., a veteran of the civil-rights movement; and Meg Whitman, the CEO of eBay, who created more than a million jobs.

Obama named two, his wife and grandmother. He also said he would consult bipartisan sources such as former Democratic Sen. Sam Nunn and Republican Sen. Richard Lugar.

Supreme Court justices they would not have nominated

McCain named Stephen Breyer, Ruth Bader Ginsburg, David Souter and John Paul Stevens.

Obama said he would not have appointed Clarence Thomas because Thomas wasn't ready at the time or Antonin Scalia, even though Obama complimented his intellect.

On sending troops to stop genocide

"Our obligation is to stop genocide wherever we can," McCain said. He added that the United States can provide materiel and support, not just troops.

"I don't think there is a hard and fast line at which you say we are going in. It is always a judgment call," Obama said. "If we have it within our power to prevent mass killing and genocide and we can work in concert with the international community to prevent it, then we should act."

On when a child secures human rights

"At the moment of conception," McCain said. "I have a 25-year pro-life record. ... I will be a pro-life president."

Obama skirted the question, saying that determining such a thing was above his pay grade and sending murmurs through the audience.

He said he supports limits on late-term abortions if there is an exception for the health of the mother. But ultimately, he said, he supports abortion rights. "I am pro-choice," he said.

On marriage

McCain said marriage should be between a man and a woman. He said he'd leave it to the states to regulate, but that he would support a constitutional amendment to ban gay marriage if a federal judge ordered all states to recognize one state's gay marriages.

Obama also said he believes marriage is between a man and a woman. But he said he would not support a constitutional amendment to define marriage that way, saying that marriage historically is left to the states to define.
