I think if Ms Laura wrote this, she had strong reason to suspect it was not a normal viral kind of illness.
I've had what could have been "food poisoning" no more than a half dozen times in my life...and I'm not a kid.Assuming that I have a pretty normal GI tract I would think that the same could be said of anyone my age..and me and Mrs Bush are only a few years apart.All I remember is that you can have cramps and might spend some time in the bathroom...if ya catch my drift.Were their symptoms like this? Worse? Much worse? Entirely different? Were they hospitalized? Did they recover fairly quickly...or very quickly?
Yes,world leaders are potential targets of killers...as are members of their family.But such folks can also,from time to time,get a bad piece of fish and suffer the consequences (cramps,bathroom,etc).
