repeat the lie often enough and people believe it.

of course, if one were to mention My Lai and lt Calley are we dishonouring the veterans?

the ironically named swift boat veterans for truth are neither truthful nor particularly swift.

one of them was shown on a previous clip from an earlier campaing standing next to Kerry praising him for his heroism under fire.
Another who said Kerry was never under fire also received a medal for being under fire at the same time. Go figure.
