You go ahead and accept Kerry's 4th explanation and remember to get a glass of Kool-Aid. He said Christmas Eve 1968. He testified to it. He said Nixon was President. It is impossible, Nixon was not President! Everyone has stated they never entered Cambodia, including people of his own boat. If he entered alone then they would have had a search party because they would have thought he might have been captured. Well then again, they may not have looked very hard. There is more proof, read for yourself.
I don't need any Kool-Aid. Kerry's own statements and diary contradict him. And Kerry brought all this scrutiny on himself by making contradictory statements. I just want to know more.
