I think it more likely that he had some not-so-aboveboard-dealings on the POW/MIA commission when they were over in Vietnam. It wouldn't be the first time that POW/MIAs have been sold down the river for political expediency.
If an extant papertrail exists, and they can corroborated, he'd take a severe, though not fatal (as most of his far-left base wouldn't care anyway) hit and possible drop a couple points in the polls.
That makes the most sense since that is where Navy Vet has his expertise.
That would be very revealing. sKerry's numbers dropping no more than 2 points after it came to light that he didn't sign a Form 180 because of his discharge "status." Scary, but revealing as to the mentality of the core left (communists) which disguise themselves by claiming to be "democrats."
We saw a REAL Democrat get up and read the left the riot act during the RNC convention. That would be Zell Miller.
The rabble we are dealing with in this election are hard core communists. Nothing more.
