All I'll say, is that Kerry, in his infinite wisdom, made a statement, that is not backed up by the demographic/educational facts about our troops.
The fact he refuses to apologize, and now says he meant the current administration, and not our troops, just shows another Kerry flip/flop.
Not only does Kerry's statement show the contempt towards service-members held by someone who almost became Commander-in-Chief, but it is also false.

On the whole, members of the military have a higher education level, higher reading comprehension, and higher cognitive function than the general population. It is also interesting to note that the South and the West have a higher ratio of service members to state population than other areas.
And golly, I'm one of them uneducated, enlisted members of the military (who is now retired), and all I have is a B.S. and an M.Ed...I ain't sure, but I might have more education than Kerry!
