If GW Bush had been off by 3 years signing and dating the Westminster Abby guestbook would it be a big deal?

Not only would it be a big deal, the press would be lampooning Bush, saying this is further proof that he's an idiot. Yet for some reason when Obama uses the whole page to sign his name, because that's how big his ego is, and then dates it wrong by 3 years, the press barely reports it.
