I fail to understand this.

What makes some of these liberal McCain supporters try to convince people that McCain is the "great knower of how to handle wars"?!

Just because the guy was a POW some 40 years ago in another war does NOT make him more knowledgeable than another person on how to handle this war.

They act as though he is: "John McCain, PhD. War"

I think it's just a selling tool and I'm not buying it.
