Even the briefest of surveys of the supporters gracing McCain's events underscores the kind of red-meat appeal he's making. Immediately after his speech in New Orleans, a pair of sweet-looking old ladies put down their McCain signs long enough to fill me in on why they're here. "I tell you," says one, "if Michelle Obama really doesn't like it here in America, I'd be very pleased to raise the money to send her back to Africa."

The diminutive and smiling old lady's friend leans over. "That's going a little too far, dear."

"Too far?" says the first. "Farrakhan is saying they were brought here against their will, and their bodies are still feeding the sharks at the bottom of the sea! I mean, really!"

"OK, sharks still eating bodies," I say, writing it all down. "Could I have your name, ma'am?"

"Janice Berg," says the first old lady. "And lest you think I'm Jewish, the name comes from Norway. Berg is 'mountain' in Norwegian. I'm part German, part French myself."

A few paces away, I catch up with a man named Ron Saucier and a woman who would only identify herself as Mary. Ron says his problem with Obama is the integrity thing. "He exaggerates too much," Ron says. "He's not honest."

"OK," I say. "What does he exaggerate about?"

"Well, like that time he was saying he had a white mother and a white grandmother," he says.

I ask him how this is an exaggeration.

"Well, he was saying . . ." he begins. "As if that qualifies him to . . ."

Despite my repeated prodding, Ron seems unable or unwilling to say aloud exactly what he means. Finally, his friend Mary, a grave-looking blonde with fierce anger lines around her eyes, jumps in, points a finger and blurts out one of the all-time man-on-the-street quotes.

"Look, you either are or you aren't," she says.

"And he aren't," Ron says, nodding with relief.
