As much as I cannot stand McCain, the leadership he demonstrated while a POW was, in fact, quite heroic.
A more correct comment would be, "Johnson is a war hero, too."
I don't know how to do links, but you might want to do a little checking as to just how much a "hero" McCain wasn't.
Three days in captivity, and he was ready to sell the US out. This was after only two missions. No hero to this Navy family!
Since McC acknowledged giving ship positions in exchange for medical treatment I can not fault him, nor can I put him in the same hero category as this man.
