John Edward's Wife Has Cancer Again

Elizabeth Edwards, wife of 2008 Democratic presidential candidate John Edwards, announced this afternoon that her cancer has recurred, this time in her bones. She was treated for breast cancer in 2004. Mrs. Edwards says that she is currently asymptomatic and that her treatment will not affect her husband's campaign and fundraising. Talking heads are already speculating on how this news may change public opinion on John Edwards. Will this news spur "sympathy" support or will it cause some to expect that Edwards will eventually be forced to pull out? Edwards is currently polling fourth nationwide, but is #1 in Iowa, the critical first primary state.
