Goldberg's realized Trump can't safely be defended; history is going to be clear on what a monumental mistake 2016 was.  But Goldberg's got this big Santa Monica conservative readership waiting for his weekly conservative bromides.  So he talks about things like "vulgarity," where he can point a finger at everybody.  All of Trump's old-time defenders do the same now: yeah, Trump may have some regrettable excesses, but so do his  critics.  This moves the discussion to trivialities of style.  Good move, when you realize that the core of this presidency--that you've been publicly promoting--is completely rotten.
