Stephen K. Bannon’s departure from the West Wing of the White House has been hailed as a victory for sanity and reason.

But is he gone? Really gone? Will the alt-right guru disappear into the mist, or into the swamp? Don’t hold your breath, dear reader.

Bannon served as “senior strategist” for Donald Trump. He is an avid “anti-globalist.” He takes pride in steering the president toward his decision to pull out of the Paris Climate Accord and for terminating the Trans Pacific Partnership.

Bannon also has been waging a feud with the reasonable elements of the Trump administration. He and national security adviser H.R. McMaster didn’t get along. It then fell to White House chief of staff John Kelly — like McMaster, a general-grade military man — to engineer Bannon’s departure.

So, he’s no longer checking in at the White House.

Bannon has returned his former post, as editor of Breitbart News, the far-right media organ. You now are allowed to bet the farm that Bannon is going to use his new/old job to undermine McMaster some more, only from outside the White House grounds. Bannon said in an interview after his departure that the presidency for which he fought is now “over,” meaning that in Bannon’s view the president has pivoted toward the “globalist” wing within his inner circle.

Bannon is having none of it, vowing to “fight for” Donald Trump, suggesting he’s going to use Breitbart to push an agenda at odds with the likes of Gens. Kelly and McMaster as well as Secretary of State Rex Tillerson and Defense Secretary James “Mad Dog” Mattis.

I believe the president needs to keep cleaning house. He needs to show other alt-right devotees — such as speechwriter Stephen Miller and supposed “terrorism expert” Sebastian Gorka — the way out the door.

As for Bannon, suffice to say this guy looks ready to exact some revenge against those who got him tossed.

Do you think this means the end of chaos in the White House? Umm, I’m thinking we’ve got a lot more of it in store.
