Stop calling Bill Barr crazy and delusional. This is a serious conceptual error. He is a deliberate propagandist who is methodically helping Trump actively weaponize the government in numerous corrupt ways, all serving the end of keeping him in power: https://www.washingtonpost.com/opinions/2020/09/14/7-ways-trump-his-cabal-are-using-government-corrupt-election/

Barr also has a genuine worldview. In declaring war on the left and claiming the executive has "virtually unchecked discretion" to prosecute for sedition, he draws on an anti-liberal tradition that glorifies the executive unfettered to act amid crises:

Of course, Barr is largely inventing the crisis -- he and other senior law enforcement and national security officials are twisting government resources to fabricate an organized domestic leftist terror threat -- to justify *Trump's* lawlessness:

Also see this, from @davidrlurie. Bill Barr is not crazy or unhinged or delusional. He has a very deep knowledge of the levers of power, as @sbagen says. https://twitter.com/davidrlurie/status/1306429513530847232
