What Songbird McCain COULD have said:
..."I was a POW - that's my business, not yours, I'm running for President of the United States, not POW" - What Sidney McCain could've said

... but he didn't.

"But after I turned down their offer, they worked me over harder than they ever had before. For a long time. And they broke me."

What does that mean "they broke me" ?

Does it mean something other than name, rank, and serial number?

How can Commander in Chief McCain command those who serve under him to give only name, rank, and serial number?
