The question is whether he will survive 35 months, let alone 35 years.
Leavenworth houses some of the worst prisoners of the military. They tend to be of limited education, fanatically loyal to the country and incredibly violent.
Maybe he wants to be put in the women's section of the prison???
Then again I've met many women in the Army of whom I would not like to be their "bitch"....
Whatever, if he's put in the men's wing, he's going to be somebodies "wife" unless he is in solitary and I doubt he would survive 35 years in solitary with any kind of sanity.
Whatever happens, Bradley Manning will be a broken and diminished husk of the person that has just been convicted, even if he does get out alive. There will be no parole for his crimes. He embarrassed too many people. In fact they could condone his release more easily if he had quietly leaked secrets to the Russians or China.
More importantly Bradley Manning will become "Bradley Who" in 2 or 3 years when the press have finally milked it of every last £ of circulation. Only brought back up as Julian Assange is in the press as his situation changes in one way or another.
