Closing statements

Posted to Live Blog: Second presidential debate by Mary Daly at 9:29 p.m., Oct. 7, 2008

Both candidates were forced to expose their weaknesses as the final question of the debate asked what they do not know about being commander in chief.

"It's never the challenges that you expect," Obama said. "It's the challenges you don't that end up consuming most of your time."

He said he has the courage to move the country in a new direction.

McCain said the challenges the country will face in the coming years will be new and different.

"I believe in this country," McCain said. "I believe in its future. I believe in its greatness."

McCain said, as his record shows, he will always put the country first.

As the debate wrapped up, Brokaw was reading the sponsors of the debate off a screen and was blocked by Obama and McCain.

"You're in the way," Brokaw said to the candidates and closed the debate.
