WASHINGTON — Hark!

What light from yonder West Wing window breaks. A bright idea has somehow emerged from the dysfunctional, dystopian Trump White House.

And from the Grim Reaper, no less.

Steve Bannon has not been partying in the Hamptons with Jared, Ivanka and Kellyanne. He has instead been lurking in his lair, scheming about a plan to raise taxes on the richest people in America and give tax cuts to the people who need them.

As Jonathan Swan wrote when he broke the story in Axios, “It’s classic Bannon — pushing a maximalist position that’s reviled by the Republican establishment.”

Conservative craniums are exploding all over town. Mitch McConnell had already been worried that Donald Trump might revert to the pragmatist who gave Chuck Schumer and Hillary donations and triangulate with Democrats.
