MR. GREGORY: Andrea Mitchell, that's a pretty clear contrast.

MS. ANDREA MITCHELL: Oh, absolutely. And, you know, there was the crisp, immediate, forceful response by John McCain, clearly in a comfort zone because he was with his base. And Barack Obama, taking a risk in going there but seeing an opportunity. And a much more nuanced approach. The Obama people must feel that he didn't do quite as well as they might have wanted to in that context, because that — what they're putting out privately is that McCain may not have been in the cone of silence and may have had some ability to overhear what the questions were to Obama.

MR. GREGORY: Right.

MS. MITCHELL: He seemed so well prepared.

Senator John McCain was not in a “cone of silence” on Saturday night while his rival, Senator Barack Obama, was being interviewed at the Saddleback Church in California.

Members of the McCain campaign staff, who flew here Sunday from California, said Mr. McCain was in his motorcade on the way to the church as Mr. Obama was being interviewed by the Rev. Rick Warren, the author of the best-selling book “The Purpose Driven Life.”

The matter is of interest because Mr. McCain, who followed Mr. Obama’s hourlong appearance in the forum, was asked virtually the same questions as Mr. Obama. Mr. McCain’s performance was well received, raising speculation among some viewers, especially supporters of Mr. Obama, that he was not as isolated during the Obama interview as Mr. Warren implied.

Nicolle Wallace, a spokeswoman for Mr. McCain, said on Sunday night that Mr. McCain had not heard the broadcast of the event while in his motorcade and heard none of the questions.

“The insinuation from the Obama campaign that John McCain, a former prisoner of war, cheated is outrageous,” Ms. Wallace said.

The pastor spoke to each candidate this week, giving the general themes. Warren decided to tell them each the first two questions in advance, about the three wisest people you know, and the biggest moral failings.
