I don't know why the President is crowing about his 45% approval.
I wouldn't. But then, I once worked for a CEO who was so proud he got a write-up in Money magazine he emailed the link to all 100K employees. So proud, in fact, he failed to notice they gave him a C-minus and was likely to run his father's company into the ground. The article was dead-on accurate, too. Remember Motorola?
Something about massive egos make that sort of thing inevitable, I suppose.
