We have public records now. We know for a fact that he joined in 1966. We know for a fact he was discharged in 1978. What we don't know is why he wasn't honorably discharged in 1972 when his enlistment was up. We know for a fact President Carter forgave all the traitors in 1978. We just don't know for a fact Kerry was one of them. We know for a fact Kerry went to give aid and comfort to the N. Vietnamese and sell out his own country. We also know for a fact he belonged to an organization that voted to kill 7 American Senators. We know for a fact that he was there at the meeting the vote took place. We don't know how he voted and we don't know how long after that vote he deny's he was a member of the VVAW. I think I would have trouble getting elected to public office if I was a founding member of the KKK, but denied having ever lynched anyone. He was a founder of a pro communist, anti American organization that voted to kill Senators. He denies being a member at that time. FBI surveillance says otherwise. We also don't know the extent of the "wounds" he received in order to get his Purple Hearts and how he qualified for them. That info is in dispute.
I think a simple yes or no answer would solve many doubts if he would just answer the question if he was less than honorably discharged in 1972. If he was, all the rest of his persona, is a sham and a lie.
