There's one of the better roundups of the John Kerry kerfuffle over at The Moderate Voice.
Reading the many posts and comments about Kerry's gaffe makes me realize that Kerry's major error wasn't the 'poorly rendered joke', but rather his response to the outcry over his perceived insult to the men and women of the Armed Forces. If Senator Lurch had merely stated “Gee, I really screwed up that joke. I'm sorry if it offended anyone and offer my sincere apologies” this whole thing would have gone away. But his arrogance got the best of him and it wasn't until other Democrats called him on it that he tried to do some damage control.
Sorry, John, too little too late.
