Define 'trustworthiness' - warranting trust; reliable. I think the slip-up is not whether or not trustworthiness is an actual word, but the fact that it is used for the opposite meaning.
He said a newly "defined" word, not a new word. So you are right, it isn't a question of whether it is a real word or not, but then again, that question was never raised.
Stacy, I believe you need to look up some of Gore's lies. They are completely ridiculous, and occasionally funnier to laugh at than Bush's slipups. As in his claim that he created the internet, and was born in a log cabin.. that he built with his own two hands.
Sounds like Gore is one french fry short of a happy meal.
I love Bush's slipups and think he's a great Christian guy and the right guy to be running our country.
Go Dubya!!!
