Well, yes.... but apparently it's no longer acceptable to look at political topics objectively. Much better to judge what people say based on ad hominem or its opposite.
I respect Krauthammer, but he is one of the “blue bloods”.
Try this analogy:
Let’s say Krauthammer had irrefutable evidence that little green men visit the Earth on a regular basis.
There is no scenario imaginable in which he would share that information with anyone for fear his reputation would be tarnished, NO MATTER how ironclad his evidence.
