The liberal group MoveOn.org is launching an ad against Republican John McCain and his joke about bombing Iran, arguing that the United States "can't afford another reckless president." The group plans to spend about $100,000 (â‚¬73,500) to air a commercial on network and some cable television stations in Iowa and New Hampshire, states that hold early contests in the presidential nomination process, spokesman Alex Howe said Friday. McCain, campaigning Wednesday in South Carolina, another early primary state, answered a question about military action against Iran with the chorus of the surf-rocker classic song "Barbara Ann." "That old, eh, that old Beach Boys song, Bomb Iran," he said. "Bomb, bomb, bomb, bomb, anyway, ah ..." His audience laughed, but MoveOn.org called the comment dangerous.
