It’s just another “We didn’t know” excuse. Don’t be surprised if we find out later Barry put that one up first.
I don’t buy the “oh, it was a mistake excuse.” Think for a minute about what this says beyond the bad decision. It means the kinds of people obama has running around his White House are the kinds of people that have Mao ornaments and might think it would be a good idea to display them. In other words, obama has dedicated fascist/communist types working for him who revere people like Mao. Sleep well, I don’t.
