John Maccain's humble character has to be rooted from his stay at the Hanoi Hilton. I think that he changed his way of thinking and dealing with daily problems while under captivity. Subcontiously he still might be trying to resist his captors and in todays equivalent it would be the Status Quo. He stands by his convictions because subconciously he believes he is protecting his comrades. So when Obama verbally attacks Maccain's political convictions, MacCain just lets the comments slide, just like the verbal abuse he tolerated while at the Hanoi Retreat. I think he really believes and has faith the American voter will see thru the political curtain put in front of us. I just hope that he chooses his retaliation battles wisely to help us all because Obama is a puppet in the green political machine rolling down the global path.
