Answer 1

This is bound to backfire on him.  His actions as a pow were treasonable.  he is the only POW that made propaganda broadcast for the North Vietnamese who did not have charges raised against him.  If he continues to use his POW time as an excuse for his gaffes, people will begin to ask why they should vote for a guy drawing full disability for PTSD.

Answer 2

I won't go there.  I'm cheering for Obama but I suppose it is fair to use anything in your arsenal when campaigning.  I agree though....it seems to be losing its strength.
