From CBS News' Aaron Lewis:
INDIANOLA, IOWA -- It was a family affair in Indianola, IA today, as John Edwards stumped yet again for Iowa voters deciding on the Democratic presidential nomination.
With children Emma Claire, 9, and Jack, 7, sitting on the bus watching movies, Edwards was joined by wife Elizabeth and parents Wallace and Bobbie at the Warren County Historical Museum. Elizabeth stood before the crowd and delivered introductory remarks.
After recognizing her in-laws, Elizabeth told the crowd about how the former senator's parents worked hard to provide for their family. She talked about Wallace working in the mills and Bobbie folding sheets.
"Is there a woman in the room who likes to fold sheets?" joked Elizabeth.
"(John) saw as they moved through and all the hurdles they had to face," she continued. "He saw that they worked hard so that he had a chance."
Family has been a constant theme for Edwards since his visit to his hometown in Seneca, S.C. last week. And they've become more of a presence on the campaign trail in recent days. Bobbie and Wallace have been in South Carolina, New Hampshire, and Iowa in the last week alone, while today marked the first time Elizabeth and the children have joined him since late October.
