COLO, Iowa: Senator Barack Obama is not big on what he calls red-meat applause lines when he campaigns in small communities like this one, just northeast of Des Moines. He does not tell many jokes. He talks in even, measured tones, and at times is so low-key that he lulls his audiences into long, if respectful, silences.
He paused carefully as he reflected on that encounter. "It reminds you why you get into politics," he said.
"It reminds you that this isn't a game."
