Sorry, I don't blame them/us.
It is like Peggy Noonan or Frum, once their masks slipped, everything they say AFTERWARDS is to be viewed with a magnifying glass.
Krauthammer is most definitely not like Noonan or Frum. I think the comparison is asinine. Noonan and Frum appear to have no root beliefs -- they both fell under Obama's spell and admitted it.
Krauthammer's very worst offense is to have occasionally complimented Obama's political successes all the while criticizing his policies. Yet there is a crowd here looking for reasons to pounce on him.
I'm pretty suspicious about the origins of the animosity.
