Bush had been trying to paint Kerry as the Pessimist and himself and the sunshine optimist. Now they can't use that with Edwards on the ticket. They have instead turned to the old standard, "They are both left of Ted Kennedy". Shock Horror headlines. It terrifies their back base to Bush tightly and lock step with him.
As for Edwards, I'll leave you with this quote from an attorney who faced him in the courtrooms many times...
Over the years, Edwards's courtroom opponents came to regard him with ungrudging awe. "He didn't have any weaknesses," says James Cooney, who faced him in about a dozen cases. "He was never underhanded. If I was in a trial with John Edwards and I ever had to pull a knife out of my back, it was only because he shoved it through my chest." In cross-examinations, Edwards's "style was gentle," says Cooney. "He never yelled at a witness. He didn't try to physically dominate a witness—when he got done, when the witnesses stood up, all their clothes fell off."http://www.msnbc.msn.com/id/5411915/site/newsweek/Don't worry...they can attack when the time is right, but they don't need to attack now. There's time for that...later when it counts.
