From The Morning GrindElizabeth Edwards returns to Iowa next week for the first time since being diagnosed with cancer following the 2004 presidential campaign. As the wife of former Sen. John Edwards (North Carolina), the 2004 Democratic vice presidential nominee, she criss-crossed the nation campaigning on behalf of the party's ticket. A week from today, Edwards will visit Des Moines for the Polk County Democrats 7th Annual Women's Event. In late September, Edwards releases a new book "Saving Graces: Finding Solace and Strength from Friends and Strangers."
