CAN'T KEEP HANDS OFF EACH OTHER Hugs, kisses to the cheek, affectionate touching of the face, caressing of the back, grabbing of the arm, fingers to the neck, rubbing of the knees... John Kerry and John Edwards can't keep their hands off each other! In the past 48 hours, "candidate handling" has become the top buzz on the trail. News photographers have been going wild with buddy photos of the two Johns. "I've been covering Washington and politics for 30 years. I can say I've never seen this much touching between two men, publicly," e-mailed one wire photographer.
