The late Krauthammer may himself been a victim of the dreaded TDS.
Trump Derangement Syndrome is a symptom of the greater Leftist disease known as the Clinical Delusion of the Lying Left - AKA the Delusional Lying Left or DLL.
TDS is a subset of DLL.
The Delusional Lying Left in turn is driven by the spirit of antichrist and those who fail to accept Christ will be carried by this force which will usher in the unimaginably horrific tribulation coming soon.
Yes, Krauthammer was indeed held hostage by his own TDS.
