The liberal group MoveOn.org is launching an ad against Republican John McCain and his joke about bombing Iran, arguing that the nation "can't afford another reckless president."

The group plans to spend about $100,000 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, answered a question about military action against Iran with the chorus of the surf-rocker classic "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.
"America has lived through six years of a reckless foreign policy," an announcer says in the ad. "We're stuck in Iraq. More than 3,000 Americans are dead. And thousands more wounded.
"Now comes John McCain with his answer to what we should do about Iran. John McCain? We can't afford another reckless president."
The group ran ads in the same states in January, criticizing the Arizona senator's support for sending more troops to Iraq.
