Bush is apparently relying on this adage in his continuing rosy descriptions of the situation in Iraq. His lies worked to get him elected over Kerry, and so why not keep on lying?
Do you think that authoritative reports about how awful the situation really is, such as this one by the retiring CIA station chief in Badgdad will change Bush's mind, or his rhetoric? Probably not.
And meanwhile, the kids--ours and theirs--keep dying.
