. . . when a mayoralty comes to be defined by fanciful notions — political labels, bike paths, french fries and other irrelevancies — forgiveness following catastrophe will be a long time coming. Especially when the mayor’s reaction to the debacle ranges from surly condescension to bewildered resentment to transparently feigned contrition. Actually, there’s scant evidence that Mike Bloomberg even now knows what hit him — apart from 20-plus inches of snow, of course. And the sanitation slowdown. Wildcat strike would be too strong a term — wild kitten, maybe. But, still, the mayor couldn’t cope. The truth is that while Mike Bloomberg was off trash talking Democratic/Republican rancor, he lost control of the New York City Department of Sanitation.
