In most political speeches, the common refrain is "my fellow citizens".
John McCain just referred to the country as "my fellow prisoners."
"Across this country, this is the agenda I have set before my fellow prisoners and the same standards of clarity and candor must now be applied to my opponent."
Late Update: For what it's worth, my own hunch is that McCain's just gotten so in the habit of peppering his speeches with gratuitous POW references that it's hard to keep the two things separate.
Latter Update: Longtime TPM Reader GG says I'm being too kind: "If a Dem had made that statement (my fellow prisoners) and in that context, the repubs would loudly proclaim the man mad as a hatter and unfit for the presidency. And judging from other recent actions, he may very well be unfit and it would not be a service to the country to gloss it over."
