"John Bolton, who as U.S. ambassador to the United Nations in 2005-2006 became a conservative icon, has not connected with Sen. John McCain's presidential campaign, though he desires to help out. Friends say Bolton was puzzled when his offers of assistance got no response from the McCain campaign. He did receive a late request to be a spokesman for McCain Tuesday in Winston-Salem, N.C., where the candidate addressed selection of federal judges. However, Bolton got the impression that he was merely being asked to attend the event and declined the invitation."
