It must be a chapter in the Democratic playbook: When all else fails, start the name-calling.

Democrats finding themselves unable to compete with the results that President Trump has achieved in just more than 200 days have begun to question his mental state and fitness for office.

They seem to have missed all of the landmarks that have been achieved by this president in just 200 days: record stock markets, 1 million new jobs added to the economy, a unanimous U.N. Security Council resolution against North Korea, a 16-year high in consumer confidence, a 17-year low in border crossings, just to name a few.

It's as if those accomplishments don't even exist.

Democrats don't want to talk about those issues because they simply can't compete. When Democrats can't compete on the issues, they resort to childish, baseless accusations of craziness.

This is not the first time we have seen this tactic.

Throughout history, Democrats have done it to Presidents Ronald Reagan and George W. Bush, Sen. John McCain, former presidential nominee Mitt Romney, and others.

When Reagan ran for office and began to get traction much to the surprise of the mainstream media, they mocked him and called him "the candidate from Disneyland" as if he was just some Hollywood buffoon not to be taken seriously, despite the fact he had run California's economy, the fifth- largest in the world, for two terms.

Even after being elected and managing not to burn the place down, the name-calling continued. In 1986, The Nation described Reagan as "demented." Christopher Hitchens called him an "idiot." Even 60 Minutes' Andy Rooney reported on a party at which guests clutched their cocktails in hysterics and said of Reagan, "I think he's out of his mind, I really do."

That sounds not unlike today's Mika Brzezinski on any given "Morning Joe" episode.

Others poked fun at Reagan saying was "no intellectual," while The Boston Globe nicknamed him "President Bozo." If you don't agree with a Republican, then he must be an idiot.

Jimmy Carter pollster Pat Caddell began to float ideas suggesting that Reagan was "in over his head," "shooting from the hip," and questioned, "Is Reagan safe?"

Sound familiar?

Because hindsight is 20/20, we now know that Reagan was not only safe, but he kept America and other nations around the globe safe. It was Reagan who asked Gorbachev to "tear down that wall" and put an end to the Cold War.

But that didn't stop liberals from continuing to play the "crazy" card into the 21st century.

Liberals suggested that Mitt Romney -- who is now someone they consider perfectly reasonable and rational -- belonged to a Mormon religion that was a "cult" deemed "weird" and "sinister" and therefore he must be crazy, too.

The liberal group ran ads comparing President George W. Bush to Hitler, claiming he was a "Nazi." Not unlike the accusations flung at Trump since the Charlottesville violence nearly two weeks ago.

But the accusations aren't limited to specific candidates or leaders. Liberals apply the broad strokes to entire parties, too.

During the 2016 election, liberal Paul Krugman addressed an appeal to "non-crazy Republicans" in an attempt to get them to abstain from voting for Trump. This is ridiculous notion as it implies that somehow all Republicans are crazy but if you're not, then somehow you must be delineated from the crowd as "not crazy."

These are just a few of the ways liberals have tried to deconstruct Republican presidents and candidates for decades.

Rest assured that with their agenda failing and their so-called "re-launch" flailing, Democrats won't stop the name-calling anytime soon.

The good news? The name-calling didn't work back then, and it won't work now.
