Donald Trump hired Steve Bannon as  his campaign manager, gave him a job in the White House, and signed an  executive order to give him a seat at meetings of the National Security  Council’s principals committee, giving him access to some of America’s  most sensitive secrets, even as his erstwhile adviser helped to make him  the most powerful man on earth.

But now the two are fighting as if they find one another deplorable and irredeemable.
Bannon  is quoted savaging multiple members of the Trump family in excerpts  from a forthcoming book by the journalist Michael Wolff. And Trump now  insists that a man he recently entrusted with a key national-security  post is crazy and has nothing to do with his presidency. “When he was  fired, he not only lost his job, he lost his mind,” the president  declared Wednesday in a statement. “Steve pretends to be at war with the  media, which he calls the opposition party, yet he spent his time at  the White House leaking false information to the media to make himself  seem far more important than he was. It is the only thing he does well.”

The answer may turn on unknowns including these:
- Is  Steve Bannon correct in his judgment that there is a big enough  constituency to refashion the Republican Party in the style of Pat  Buchanan by electing anti-globalist, anti-Muslim, anti-immigration,  anti-establishment candidates to the House and the Senate? Or is  Trumpism inseparable from Donald Trump himself and his singular  celebrity and charisma? 
- If Buchananite primary challenges are possible, is Bannon savvy  enough to judge which candidates are viable and which are not because,  for instance, they dated young teenagers in their 30s or embraced  anti-Semitism? 
- How secure is Bannon in his perch at Breitbart? Is it in the financial interest of the site to break from Trump? Could it do so and retain its audience? 
- What is the most damaging information that Bannon has about Donald  Trump, his eldest sons, Ivanka Trump, Jared Kushner, and others in their  orbit? 
- If Trump continues to sign legislation and appoint federal judges  like an establishment Republican, even as he wages a scorched-earth  culture war on Twitter and elsewhere, will that be enough to satisfy  loyalists in his base? 
- Will the billionaire Mercer family give him money in the future? 
But it may be that Bannon has destroyed himself regardless. I’m  hesitant to reach that conclusion because I do not understand the course  that he has chosen, but I don’t understand it precisely because it  looks so much like self-immolation. His words seem likely to permanently  alienate both the 
National Review-wing of establishment conservatism that already hates him and loyal Trump supporters.
</section><section id="article-section-3">The Bannon quotes excerpted in 
The Guardian, pertaining to a meeting at Trump Tower with a Russian lawyer and Trump’s inner circle, are particularly inflammatory.
My colleague David Graham 
characterizes their significance:
	
	
		
		
			In describing the Trump Tower meeting as “treasonous” and   “unpatriotic,” Bannon becomes the first major Trump insider to say what   is at this point clear to anyone willing to look at the facts: Whether   or not there were any crimes committed, Trump aides colluded with   Russia. The pattern runs from George Papadopoulos’s conversations with   Russian agents, through the Trump Tower meeting, and up to Michael   Flynn’s conversations with then-Ambassador Sergey Kislyak, about which   he has pleaded guilty to lying to FBI agents.
		
		
	 
At 
Hot Air, Allahpundit 
asks, “What is Bannon thinking, 
legitimizing the Russiagate investigation  when everyone else in populist media has spent a year insisting it’s a  witch hunt based on lies and innuendo? At the very least you’d expect  him to blame people like Carter Page and George Papadopoulos for driving  the suspicion, not the Trump family. He might have gotten away with  slamming Jared since their feud is public knowledge but going after Don  Jr is an attack on POTUS himself. He’s practically forcing 
Breitbart fans to choose between him and Trump now, particularly by using a term 
as loaded as ‘treasonous.’ And 
Breitbart’s not challenging the veracity of the Bannon quotes, mind you.”
