Seeing as they screwed up on the shameful bowing before the Emperor in Japan, and now in going over the official White House list, that a White House Official told journalist Jim Fallows on the Atlantic just several days ago that Obama was in a "funny" jacket when at the APEC group photo in Singapore (hint, nothing funny at all about it to Singaporeans as it was their national dress for men), and now I spot a misspelling of the last name of one of the guests for the State Dinner, etc. etc., these amateurish idiots cannot do ANYTHING right when it comes to anything at the intersection of Quality Control and Diplomacy. What makes you think they were "in on it"? I think it is blatant imcompetence, probably peppered with political correctness.
Now think of all the other goofballs that are going to try this to see if they can get away with it.
I think they are going to be on a reality show Wives of DC or some such show like the ones from New Jersey, New York, Atlanta, etc. Means it was a set up by the network. They had to be on the list and approved by the Secret Service before they even got out of their cars or on to the grounds even if they came in with some network honco.
