Here's how to slam your opponent without appearing at all negative:
"I honor his service in Vietnam," Edwards said. "In 1969, I was sitting around the kitchen table with my parents trying to figure out how we would pay for college like so many Iowans do. ... And that is a difference between me and Senator Kerry."The News & Observer then spoonfeeds us the comparison:
Edwards attended Clemson University and then transferred to N.C. State when he could not get a football scholarship. Kerry attended prep schools and Yale University.
