Almost everyone eventually deserves to be put out to pasture. Maybe Krugman is at that point. If he’s there long enough, Jamelle Bouie will reach that point.
It shouldn't be true, because writing ability and ideology are separate things. But I almost never see anyone say that someone they disagree with writes well. (I think Douthat and French have many well-written columns I disagree with.)
Krugman is still better than all of the right-wingers, combined. Why should he be "put out to pasture," unless there's something he's gotten wrong, which IMHO he hasn't? Can't say the same for Douthat, Brooks, Stephens, Dowd, or Friedman. They've been hacks for years.
