Kerry had no respect for the medals or the military. This is why it did not disturb him to obtain them over any excuse. McCain's claim to fame is his own imprisonment and the ability to attack sKerry will mean they will attack McCain's heroics in 2008.
It must be an issue of politicians sweating their service.
(odd how nobody asked medal winner oliver north about this issue.)
Kerry would jump in and say how he brought North down singlehandedly, yada, yada. North would be destroyed all over again
Later, Kerry ordered documents detailing information on Vietnam soldiers who are still MIA to be shredded. He and McCain were partners in that venture.
