CHARLES CITY, IA - In his first event of a two-day swing through Iowa, Edwards kept up his assault on Clinton -- but added a new, more subtle offensive against Obama.
Running down his opposition to the recent Peru trade deal, Edwards mentioned that Obama supports it, and added that he hadn't heard what Clinton's position was. Edwards rarely mentions Obama on the trail, but Mike Signer, who handles Edwards' foreign policy, also questioned Obama's position on Iran in an interview with MSNBC's Norah O'Donnell on Friday.
Regarding Clinton, Edwards said, per his campaign: "For the sake of hard-working families in Iowa and all across America, I hope that Senator Clinton will finally take a stand, do what is right and join me in strongly opposing the Peru trade deal."
