Brokaw emphasizes the red and green lights

With the candidates taking extra minutes for rebuttals, Tom Brokaw has to keep reminding them of the time limits.

"I don't know if you guys have noticed the lights around here," Brokaw said.

Each candidate has taken extra time on questions because of accusations by the other candidate that needed explaining, such as McCain claiming Obama would raise taxes.

In his next response, McCain cut off early and said, "Look Tom, I stopped and you weren't even waving."

At the Republican watch party in Columbia, Tim Grenke, who is on leave from Kosovo, said he was glad the candidates were taking the time to critique each other.

"I appreciate the fact that they're telling people to look at their records," Grenke said.
