“The world is laughing at us. They’re laughing at the stupidity of our president.”

— Donald Trump, October 2016

Stupid is as stupid does.

And Republican lawmakers probing Trump’s ties to Russia threatened subpoenas over the executive branch’s stonewalling.

In one of the presidential debates, CNBC’s John Harwood asked Trump if he was running “a comic book version of a presidential campaign.” Now Trump seems to be running a cartoon version of a presidency, and he’s Elmer Fudd. His proposals could, if successfully implemented, be ruinous. But so far, at least, Trump has been mercifully incompetent.

Trump’s first national security adviser, Michael Flynn, lasted just 24 dayson the job after misrepresenting his contacts with Russia. Attorney General Jeff Sessions falsely testified that he’d had no contacts with the Russians, forcing his recusal from Russia investigations once the truth came out.

Trump’s nominee to be labor secretary withdrew in the face of broad opposition. His education secretary, who suggested that schools need guns to defend against grizzlies, was confirmed only when the vice president broke a tie vote.

Trump blamed a “so-called” judge for striking down his first travel ban and proposed blaming the court system if there was a terrorist attack; his own Supreme Court nominee called such remarks disheartening.

Trump conducted sensitive diplomacy over a North Korean missile launch with the Japanese prime minister surrounded by diners at his Mar-a-Lago country club, one of whom posted online a photo of the man carrying the nuclear football.

Trump, after inflating the crowd size at his inauguration and embracing a conspiracy theory that 3 million to 5 million Americans voted illegally, falsely accused the media of not covering terrorist attacks. The White House then produced a badly spelled list of attacks, most of which had been covered. Conway invented one attack, the “Bowling Green massacre.”

Conway pitched Ivanka Trump’s fashion line on Fox News. Taxpayers have subsidized millions of dollars’ worth of expenses related to Mar-a-Lago and the Trump sons’ foreign travel.

Trump marked Black History Month with remarks suggesting he thought abolitionist Frederick Douglass was still alive.

Trump opened a rift with Australia in an angry phone call with that ally’s prime minister. He provoked the Mexican president to cancel a trip to Washington, and he baffled the Swedes by alluding to fictitious refugee-related violence “last night in Sweden.” Britain postponed a visit from Trump in hopes that anti-Trump protests would cool.

This tragicomedy adds irony when you consider that the main character is the same one who campaigned by saying “they laugh at our stupidity” and “we are led by very, very stupid people” and “I have the best words, but there’s no better word than ‘stupid.’ ”

Now the world has reason to laugh at us — because we’re with stupid.
