This is a breaking story, so too early to get excited. If it is true, look for the Democrats to question the timing of the discovery's announcement.
In fact, I think that from here on out in the campaign, every bit of positive news for Bush that emerges from Iraq will be called "the July surprise," or the "August surprise," "September surprise," and so forth. Kerry and Co. are surely very nervous about any good news that might come out, whether it's bin Laden's capture or the discovery of Iraqi WMD in Syria.
UPDATE: So far, looks like no story, at least according to Reuters. Thanks to Power Line.
