Edwards Running?

Former Sen. John Edwards was on Hardball today looking very casual in everyday clothes in front of a house in New Orleans that was being rebuilt. He said he "was wrong" for voting for the use of force in Iraq. Edwards then preceded to rip into Bush and the decisions he has made. At the end Matthews asked if he was running again in 2008, which Edwards replied,"I haven't made that decision yet." Why else would a lawyer pretend to be Bob Villa. I got nothing against Edwards, but haven't we been down that path before with him.?
