I agree with you, but us to be right the person in question actually has to be under constant life threatening torture, and that seems to not be the case. Why don't you read the transcript? The doctor notes that McCain had recovered from the injuries he sustained in the ejection and only has some minor problems with one of his hands... not exactly the "tortured so bad he couldn't raise his arms" condition we have been led to believe is the truth.
Also, McCain has always claimed that all he did was sign some confessions, and when asked about the military command structure he said that he fooled his captors by giving them the names of Green Bay football players, but in that interview he's telling the guy all about who does what... and he's no talking about football players.
Another untruth seems to be what McCain sain in an interview with US News and World Report,
John McCain, Prisoner of War: A First-Person Account - US News and World Report, in 1973 where he says "I said, "O.K., I'll give you military information if you will take me to the hospital." Then at the hospital he says "Sometime later, "The Bug" came rushing into the room, shouting, "Your father is a big admiral; now we take you to the hospital."
Now think about that. This is 1967, in the third-world nation of North Vietnam. There is no internet... no electronic databases... barely even any telephones... but the NV are able to determine who John McCain is within four days of his arrival at the prison. McCain makes it sound like the NV somehow discovered his identify, but there's only one way they could have identified him that quickly - he told them who he was!
So, he promises to give up military information in return for medical care, he gets medical care. What did he give up to get it? According to some he gave up all the entry/egress routes for attacks into North Vietnam, along with lists of key targets. This is just allegations, but what is factual is that shortly after McCain's capture, the NVs relocated air defenses to positions along the entry/egreess routes an to near key targets of Operation Rolling Thunder, and casualties increased over 60%. An amazing coincidence don't you think? Previous to McCain's capture, the NVs had been taking a pounding due to their poor locating of air defenses, after McCain's capture they reposition and start pounding our guys but good. Yeah... must be a coincidence.
Anyway... if McCain is going to use his time as a POW to justify people voting for him, then the people ought to look at what he did as a POW.
