The Wall Street Journal refused to endorse in the 2016 presidential race, but it hasn't stopped them from railing against President Donald Trump since he took office.

In a scathing op-ed, the editorial board explained that Michael Wolff's latest book 'Fire and Fury' only "reinforces the contempt they have for Mr. Trump." However, the knowledge that Trump is an alleged "f*cking moron" or a "f*cking idiot" is fairly well-known already.

"We also knew that Mr. Trump knew almost nothing about government or policy, that he reads very little, and that he is a narcissist obsessed with his critics. Any sentient voter knew this on Election Day," they wrote.

They went on to say the book has done nothing but confirm Democrats' thoughts and cause those Trump defenders left to be stubborn and more relentless in support of their candidate. The one thing it's done is try and tell Bannon's story that he was the one responsible for winning the presidency. After all, if Trump is as mindless and empty-headed on the facts and deficient, at best, on decision-making sills, he couldn't possibly have won it on his own.

"The surprise is that Mr. Trump kept Mr. Bannon around as long as he did," The WSJ wrote. "Mr. Bannon fed Mr. Trump’s political paranoia and his worst policy instincts such as tearing up NAFTA. Mr. Bannon resembles Pat Buchanan, a protectionist predecessor to Mr. Trump, in being at heart an American declinist. He rails against the present in favor of a more idyllic past. Recall the 'American carnage' of the Trump inaugural."

The appeal to Trump, according to the WSJ is that he has a "cult of personality." Without actual policies or definitions of Trumpism, they focus on him.

To them, the cruel break-up as a political relief for those who feared Bannon's extremist ideology.

"The President’s worst mistakes have come from heeding Mr. Bannon’s desire to blow up the status quo first and pick up the pieces later—think of the travel ban. The President’s successes have come when he has bursts of discipline while pursuing the more conventional conservative agenda on judges, tax reform, regulation and foreign policy," the op-ed went on.

However, if Bannon's own stupidity backfires to isolate him from pushing candidates in 2018, the WSJ said that it would probably be better for the Republicans, including Trump.
