As the government shut down over the holidays, the President appeared to barricade himself in the White House and tweet about his dire fate.

"I am all alone (poor me) in the White House waiting for the Democrats to come back and make a deal on desperately needed Border Security," he wrote. "At some point the Democrats not wanting to make a deal will cost our Country more money than the Border Wall we are all talking about. Crazy!"

Writing in the Los Angeles Times Tuesday, conservative columnist Jonah Goldberg observed that the President's poor character—as evidenced by the government shut down and his reaction to it—might doom his administration.

"As we celebrate Christmastime [sic] amid an unnecessary and indefinite government shutdown and the worst December for the stock market since 1931, I’m reminded once again of my longstanding prediction: The Trump presidency will end poorly because character is destiny," Goldberg writes.

He lists the qualities associated with good character, which seem to be largely missing in the Trump administration: "decency, politeness, self-restraint, commitment, honesty, cooperativeness and the ability to think of others’ well-being."

Conservatives might balk. "Weirdly, it’s gotten to the point that when I say President Trump is not a man of good character, I feel like I should preface it with a trigger warning for many of my fellow conservatives," he writes.

Goldberg points to an array of ways that fellow conservatives have defended the president's character, from minimizing his Twitter presence to citing his authenticity and apparent love for his children.

But Goldberg concludes that those are irrelevant tests of his character and lists the more pertinent qualities.

"But his refusal to listen to advisors; his inability to bite his tongue; his demonization and belittling of senators who vote for his agenda; his rants against the 1st Amendment; his praise for dictators and insults for allies; his need to create new controversies to eclipse old ones; and his inexhaustible capacity to lie and fabricate history,' he writes. "All this springs from his nature.'
