This is a video clip from 24 Nov. 2004. The bit on condescension begins around 2:24. So Obama knew that the appearance of condescension was a killer in elections. A lesson obvious from the Nov. 2004 election. So how did he screw the pooch?
I think he can't help himself. He has a political persona and then there is the man underneath. And every now and then the man underneath leaks out. Keep faking sincerity Obama, until you get it Wright. Or as Flanders and Swann used to sing: "Always be sincere, whether you mean it or not."
