One tries to figure out 
explanations for these things.  It's hard.  At different times I'd probably have different theories.  Now I'll lean on the fact that one is a Village dweller of good standing and one isn't.  I have no idea if it's true.  But, yes, certainly my weighting of the criminal investigation of a sitting senator and the criminal investigation of some guy with no political power differs from that of the editors of the Post.
