This is based on a 10% response. The combat troops are sharing a computer with a company and have little time to take surveys. They send their e-mails to their families and let the next guy in line get on.
I don’t have good facts on this, so just offering what I read somewhere else (do not remember where), but it was said that this survey, which gives such “wonderful” results was done after the CA court case that theoretically invalidated DADT, at which time the troops were led to believe that repeal was a certainty. Even if there is any validity to the survey results, I have to believe that the responses would be different if DADT seemed to be solidly in place into the future, as opposed to having the appearance of being repealed.
But we are dealing with an administration and Gates, who will tweak and twist the numbers in whatever way serves their needs, so it does not matter, I guess.
