(CNN) - Retired Gen. Wesley Clark, appearing on CNN's "The Situation Room" Tuesday, continued to press the argument that John McCain is not suited to be commander-in-chief, and took aim at the Arizona senator's "judgment."
"I've never said anything to dishonor John McCain … I like him. But I will say this, that when it comes to being President of the United States, it's about judgment," Clark told CNN's John Roberts. "And I've seen stronger judgment from Barack Obama, despite the fact that he doesn't have military experience than I've seen from John McCain despite all his worldly travels.
"To me, this is about, and I hope the American people will make the decision based on judgment," he added.
Clark also criticized Orson Swindle, a McCain surrogate and former Vietnam POW, who blasted Clark's record as Supreme Allied Commander of NATO.
"I don't know Orson. I'm sure he's an outstanding man and did a great job in uniform. He doesn't know me either," said Clark.
"But I did in my last command as the head of the forces in NATO, lead the forces of NATO in the fight to stop ethnic cleansing in the Balkans. We did win a war. We bombed for 78 days … we did it without the loss of a single American soldier … We did it with a combination of diplomacy and force," he said.
Clark also discussed his support in 2004 for John Kerry, namely on his military experience, and how it differs from McCain's.
"John McCain basically served honorably while in uniform, he did everything the country could have asked," Clark told CNN. "What John Kerry did is John Kerry got out of the uniform and took a judgment, a judgment I didn't agree with at the time, but he had the moral courage to stand up for himself and oppose the conflict in Vietnam.”
