Why would you think King Abdullah would have released that info long ago, it is not like that info mattered at all to him. I honestly don't think King Abdullah would have cared if Kerry had won, mostly because the president has been giving Abdullah alot of flack trying to get him to reform democratically. I don't think Abdullah would have released that info earlier, because I don't think he cared if the president was re-elected or not.
It has nothing to do with GWB's reelection. IMHO King Abdullah relayed info to GWB prior to Iraqi Freedom during a visit to the Crawford Ranch. This was prior to Powell's speech at the UN. Sometime around March 2002.
