Bush's Guard Memo

If the documents are forgeries (and it appears that they may well be), why hasn't the White House issued a blanket denial of the contents of the memo?

a) Bush's operatives are smart enough to realize that any response will become part of the news cycle and are allowing the forgery stories unimpeded play on the airwaves.

b) Bush is too busy protecting us from terrorists to respond to cheap shots.

c) Bush's campaign is afraid that the contents of the memo may be accurate.

Just wonderin'.

I think it is probably a. But I don't know if I could keep myself from setting the record straight if someone blatantly, verifiably lied about my guard service.
