John McCain's qualifications."](CNN) - Sen. John McCain's campaign on Monday called retired Gen. Wesley Clark's remarks that McCain lacks command experience "the lowest form of politics."
Clark, a military adviser for Sen. Barack Obama, questioned Sunday whether McCain's military experience qualified him to be commander in chief.
The McCain campaign has called on Obama to condemn the comments.
"I think it's kind of sad," McCain campaign manager Rick Davis said Monday on CNN's "American Morning."
