A strange juxtaposition, via CNN: The senator from Massachusetts also took aim at Dean over his comments questioning Kerry's judgment for voting against the Persian Gulf War in 1991 and for backing a 2002 Senate resolution authorizing the use of force in Iraq. "Mr. Dean is completely wrong," Kerry told CNN's "American Morning." He complained Dean had promised a few days ago to "stop running a negative attack campaign." "Within two days, he attacked [Federal Reserve Chairman] Alan Greenspan, he attacked every single candidate, he's attacked me... Kerry had complained earlier this week that Dean's tax plan and foreign policy are "just going to kill us." Meanwhile Dean and Kerry both try to stake out "comeback kid" territory: With voting under way in New Hampshire, Sen. John Kerry -- who still rejects the front-runner label -- said a win Tuesday in the first state Democratic presidential primary would be a major boost to his campaign. Kerry, who surged to a surprising victory in last week's Iowa caucuses, said, "This is the comeback trail. If I win here, I think that's enormous." ..."I was the front-runner in this race for a long time," Dean said. "Everybody threw everything they could at me. One of the things John will have to learn as a front-runner is to stop whining when people say something different about him."
