President Obama: Time Traveler?

Today, President Obama was partying with the Royals as tornadoes have killed more than 125 people, there is flooding in the Midwest with both incidents doing billions of dollars in damage. Most normal people would not be partying with the Royals, but not Obama- it's all about him.
Anyways, when he signed the guest book today, he signed the book with the date of "24 May 2008"
From the New York Magazine: "This is how President Obama signed the guestbook at Westminster Abbey earlier today, where he got a tour from the Very Reverend Dr. John Hall and laid a wreath on the Grave of the Unknown Warrior.
It is a great privilege to commemorate our common heritage, and common sacrifice.
Barack Obama
24 May 2008
It was really nice until he got the date wrong by three years. Granted, 2008 was a great year for him, and we might try to live it for as long as possible, too, if we were him. Also, though, he may have had a stroke." http://nymag.com/daily/intel/2011/05/president_obama_has_no_idea_wh.html
Apparently, there wasn't a teleprompter near by to help him with the date.
If President Bush, Sarah Palin or any other GOP politician did this, it would be front page news, SNL would be doing skits, and the media will be lampooning him, just like they did to Dan Quayle.
President Obama: worst president ever and not too bright either. Must have gotten his law degree from Cracker Jack.
