…and his critics’ derangement syndrome.

Anti-Barr polemics dwell on the parade of horribles that might come from his tenure at Justice, without pausing to consider that a norm-busting violation of the rules targeting a politically inconvenient individual already occurred — it was the abusive FISA surveillance of former Trump campaign official Carter Page.

The supposed institutionalists and civil libertarians who are piling on Barr are more outraged that the attorney general wants to get to the bottom of this abuse — and related 2016 investigatory overreach — than by the abuse itself.

It’s no wonder that Barr has a poorly disguised contempt for his critics, many of whom are so inflamed by their opposition to Trump that they’ve lost any sense of standards. In a peppery speech to a Federalist Society conference last year that is now one of the counts against him, Barr rightly warned that “it is the Left that is engaged in a systematic shredding of norms and the undermining of the rule of law.”

As has always been the case.
