The Atlanta Journal-Constitution 03-23-07 Edwards' decision confounds experts: Move to continue campaign could be seen as either bold or cold but would increase his health care expertise. BYLINE: SCOTT SHEPARD; Cox Washington Bureau Washington --- While John Edwards said Thursday his campaign "goes on strongly," the unusual nature of the situation confronting the former senator from North Carolina confounded political experts trying to assess what impact it would have on his attempt to win the party's nomination next year. "It's sad and tragic and very unusual," said Steffen Schmidt, a political scientist at Iowa State University who doubles as "Dr. Politics" on a popular call-in radio program in Ames, Iowa. "Some people are saying it is kind of a cold move, kind of out of character for a man so family-oriented. Others are saying it's a very bold move, one that shows a lot of courage. I suppose it could go either way." But Diane Bystrom, the author of 11 books on politics, including "Gender and Elections," said Elizabeth Edwards' illness could result in key constituency groups in the Democratic Party "being drawn to and identifying with" the Edwards campaign, at the expense of Sen. Hillary Rodham Clinton of New York. Bystrom's research has detected a pattern of male politicians using breast cancer as political shorthand for appealing to female voters, especially if their opponent is a woman. "And here, you've got a man running against a very formidable woman," she said. "If there is any upside out of a serious illness, it is that Edwards will have unique credibility to discuss health care in America," said Darrell West, a political science professor at Brown University and developer of the Web site InsidePolitics.org. But Debbie Walsh, the director of the Center for American Politics and Women, said there is no way to accurately predict how any constituency is going to react politically to the recurrence of Elizabeth Edwards' cancer. "It probably makes them, as a couple, seem more real, because they are experiencing what so many other Americans have experienced," she said. "But she was already so real to voters." And popular, according to Frank Luntz, the noted Republican pollster who already has done extensive political research on the 2008 presidential campaign. "Elizabeth Edwards is probably the most popular political spouse in Iowa," he said.
