Elizabeth Edwards hits the trail

VINTON, Iowa -- Elizabeth Edwards and her three children flew from Raleigh to snowy Iowa today to join her husband's final push to Thursday's caucuses.



Edwards traveled over snow-packed roads to speak to around 30 people at a nursing home in this tiny town. Her first campaign appearance since before the holidays came in part to show people she's still up to it. Earlier this year she was diagnosed with incurable cancer.



"I think people actually need to see me, that I'm healthy," she told a reporter.



She's undergoing treatment for the cancer and showed a bruise-like spot on her wrist where she's been injected. Other than "a few side effects," she says, she's feeling fine. She didn't seem to lack energy, answering questions in Vinton in her usual quick-paced style.



She called the Iowa campaign a "dogfight" and said she plans to join her husband for the duration. In Vinton, she posed for pictures and handed out autographs.



"She's awesome," said Sonia Kach, 42. "She'd make a wonderful First Lady."
