White poppies. Sometimes something rings a little bell amid the gloom, like a bird singing after a catastrophe, or a light in a raging storm. It's a symbol of peace, first introduced in Britain by the Co-operative Women's Guild in 1936.

"General Petraeus is a military man constantly at war with the facts," began the MoveOn.org attack ad against Gen. David Petraeus back in 2007, after he had delivered a report to Congress on the status of the war in Iraq. George W. Bush was president, and MoveOn was accusing Petraeus of "cooking the books for the White House." The campaign asked "General Petraeus or General Betray Us?" on a full-page ad in The Washington Post. MoveOn took tremendous heat for the campaign, but stood its ground.
