From the NY Post:
Black's hiring took on a symbolic meaning far greater than the job itself. The secretive, unpopular choice of someone who was too far outside the box opened a window into Bloomberg's state of mind.
It wasn't a pretty picture. Starting with his manipulation of the term-limits law, Bloomy has been erratic. Even more telling than scandals like CityTime, the mayor is too flip about public concern.
Through his discipline and the persistence of talented staffers, Bloomberg mostly kept that imperious persona hidden for eight years. But the third term, staffed with a third team, has worked on him like a bottle of wine: It loosened his tie and his tongue.
He acts as if the job is somewhere between an entitlement and a consolation prize and that he can do it on automatic pilot. He's tuned out dissent and, in trickle-down fashion, some aides assumed a license to distort facts and trample truth.
From the Daily News:
So now Bloomberg, the only person in the whole city - besides Cathie Black - who thought [Cathie] Black should be schools chancellor despite her spectacular lack of qualifications, fires her because she isn't qualified for the job. It really is kind of wonderful. Bloomberg replaces Black with a different kind of crony, a City Hall insider named Dennis Walcott, apparently having just remembered that Walcott went to public school.
The mayor of New York is suddenly supposed to have turned into a very big guy because he said, "I take full responsibility for the fact that this has not worked out." It was a huge relief, of course, to people all over town who started to worry that they were to blame for Black's appointment.
This is apparently how low we currently set the bar for our elected officials: We're expected to carry them around the room when they admit they made a mistake...
The mistake was a third term for Bloomberg, the sense of entitlement he brought to the whole process. He is still running television commercials even though he is no longer running for anything. Commercials about Bloomberg, paid for by him. Perfect.
