According to my caller, the news is that this colonel discovered the real reason why the Bushes all had such sudden onset of autoimmune disease -- a sudden supply of "bad water" at Kennebunkport, the family's Maine vacation home. While my caller had no details on the "bad water," he indicated that the family of the retired colonel assured him that the "bad water" was a covert assassination attempt by Saddam Hussein against Bush.
No way to track down the veracity of this particular "theory," but this was definitely not the typical reader email I get around here! Some would theorize that the "bad water" and resulting autoimmune crisis for the Bush clan was probably due to a less sinister but equally dangerous domestic danger -- a plume of perchlorate contaminating the Kennebunkport water, or another equally unhealthy environmental toxic exposure.
By the way, there are reports that autoimmune diseases run in the Bush family in general, and I've theorized in the past that current President George W. Bush's episode of choking on a pretzel may even point to an as yet undiagnosed thyroid condition. See: Grave Concerns: President Bush's Health Timebomb? Is He, Like His Parents, Facing Thyroid Disease?
