So, let me get this straight: you're saying the use of UNPRECEDENTED is in all actuality UNSUSTAINABLE?
(Sorry; buzzword metahumor.)
Unsustainable, of course! Not only that, unnecessary, unrealistic, unbelievable, inappropriate, unproven... I could go on. It becomes hilarious as you hear all the talking heads starting to use the same word about him and everything he does, even when he has done NOTHING that remotely qualifies as unprecedented. That word used to mean: never before seen or without precedent, something entirely new. With the exception of his race with his election to the highest office, there is NOT anything he's done that can truthfully be said to be without precedent. It's like when the media got the word "gravitas" as speaking of George Bush's lack thereof. Before too long everyone was using it. With this pet word of Obama, for Obama, we keep seeing it used for the past four years. It's getting OLD and no longer means anything. It's a joke! I'd like to see in the yearly list of words we need to get rid of.
