Administration's Chief Speecher Steps Down
Michael Gerson announced this week that he will be stepping down from his post as chief speech writer for President Bush. Mr. Gerson has been writing for the President for seven years and has left an indelible mark on the nation's oratory. We were lucky enough to get a copy of his letter of resignation:
[i]Dear Mr. President,
First, I want to express my gratuity for the trust you placed in me and for the many opportunistics that I had to travel the great nations of the world including China, Russia and Africa. It was an honorary to stand by your side as you fought for every American's right to put food on his family.
Not many individuals get the chance to work for the nation's chief decider so I will always cherish not only the good times, but the other times before, for it is those times that test how we feel about the times that are.
I have the utmost respectfulness for you, Mr. President, and know you to be a man of firm convicts who would never think to disassemble. But the time has come for me to move on, perhaps to write on one of the Internets (although deciding which one will be difficult), or prepare a children's textbook on structure sentence proper.
I have certainty that future generalizations will look back on these years and find historicality and will surely come to realize that yours was an administration that ensured that America would always remain a nation where wings take dream.
President Bush was said to be "fully of sorority" to see Gerson go as he was one of the few people who truly understood him.
Democrats responded to Gerson's departure by noting that he was part of an overall "culure of correlative conjunctions." Also, something about WMDs.
