RALEIGH - From the moment she stepped out of the chauffeured SUV at a Glenwood South pizza joint, Chelsea Clinton was thronged by Hillary Rodham Clinton supporters looking for autographs and pictures.

She held babies. Worked the room.

But she wasn't the one changing people's minds during the campaign stop at the Mellow Mushroom Sunday.

That was done by Erika Alexander. Alexander, 38, is best known for parts in the sitcoms "The Cosby Show" and "Living Single." Her role on Sunday was a self-described Hillary Rodham Clinton surrogate and, unlike Chelsea, Alexander didn't hesitate to drill her points home with anyone who would listen.

On the deck outside the restaurant, Alexander homed in on two Barack Obama supporters, Troy Mintar and Chris Leaston. She recited Clinton's civil rights work going back to the Carter Administration as proof of her record.

"If you're going on feeling, I don't know how she can help you -- unless you like blondes," Alexander said, challenging the men to base their choices on Clinton's record.

After Alexander left, Mintar's decision for Tuesday's primary was shaken.

"She made a lot of good points," he said. "I don't know now who I'm going to vote for."

Dressed in a seersucker suit jacket and laceless low-top blue Chuck Taylor tennis shoes, Alexander followed Chelsea Clinton's photo ops looking for the yet-to-be converted.

Her job on the campaign, she said, is reaching out to black college students.

"They send me into the belly of the beast," she told a group of Clinton supporters on the patio. "You get two or three in 20" thinking about their choice, she said.

Alexander didn't shy from confrontation. She spent 15 minutes sparring with Dennis Conners, who was visiting with his theater troupe from New York.

Conners, 23, grilled Alexander about Clinton's ties to New York before she went to the U.S. Senate. Alexander didn't blink.

"What about Arnold Schwarzenegger?" she asked. "He's been a good governor for a lot of people in California. He came from Austria. Should the people of California not be able to vote for him?"

In the end, Alexander gave Conners a peck on the cheek and wished him well.

As for the younger Clinton, her toughest challenge came from the diners on the patio.

"Chelsea, we got Jagerbombs," a voice from the tables called out.
