It’s kaput.

After three months of cackling along on “joy!” and her media shills’ green brat pixie dust, the Harris-Walz bus blew a head gasket this week.

The fatal tell: Adolf Hitler.

Today, Germany’s führer from 1933 to 1945 is dimwit shorthand for “evil.” The jab carries all the intellectual heft of a “your mom” comeback.

So it is no surprise that on Wednesday, Vice President Kamala Harris stood outside the front door of her residence at the U.S. Naval Observatory and declared, “It is deeply troubling and incredibly dangerous that Donald Trump would invoke Adolf Hitler … this is a window into who Donald Trump really is.”

Why deploy Adolf now? Kamala’s kampf: the latest polls from The Wall Street Journal (Trump +3), CNBC (Trump +2), and Forbes (Trump +2) are detonating with mushroom clouds of despair across Karenland. It’s DEFCON 1 at the DNC.

Opens Democrat playbook. Let’s see here. Losing? Reference page 2: compare your GOP opponent to the genocidal madman and failed watercolor artist who took over Germany 91 years ago and triggered the biggest loss of life in human history.

It’s a well-worn Dem ruse.

Former President Donald J. Trump was still in diapers on the eve of the 1948 election when President Harry Truman compared Thomas Dewey and his running mate Earl Warren to Hitler, warning, as The New York Times reported, that if they were to win it would “bring a Fascistic threat to American freedom that is even more dangerous than the perils from communism and extreme right ‘crackpots.’”

When Sen. Barry Goldwater accepted the Republican nomination in 1964, Democratic California Gov. Pat Brown said the “stench of fascism is in the air.” George McGovern likened Nixon to Nazis in 1972. Rep. William Clay of Missouri blustered that Ronald Reagan was “trying to replace the Bill of Rights with fascist precepts lifted verbatim from Mein Kampf.”

In 2005, Al Gore claimed the George W. Bush administration unleashed “squadrons of digital brownshirts.”

And on and on. From Glenn Youngkin to Ron DeSantis, to Mitch McConnell, you’re not doing your job as a Republican if Democrats don’t compare you to the fascists.

If leftists hadn’t killed humor in their own Orwellian war on language, they might laugh at the irony.

After all, it is Democrats who style themselves as America’s champions of big government, high taxes, government-control of business, state-controlled media, state-run healthcare, Keynesian economics and socialism.

You too mein herr? It’s glossed over by blue-haired baristas that Nazis also adored big government, high taxes and state-run everything. There’s also the left’s troubling obsession with race and gender defining the core of one’s identity. See President Joe Biden: “You ain’t black.” Few grasp that “Nazi” was short for Nationalsozialistische Deutsche Arbeiterpartei, the National Socialist German Workers’ Party.

But to Democrats, projection is the better part of valor — it’s those damned Republicans who are Hitler, Nazis, fascists, and err, socialists.

Dewey, Goldwater, Reagan, et. al. were just the windup. The biggest Hitler of them all is Donald J. Trump.

Naturally, the left compared Trump to Hitler in the 2016 election (and Hillary Clinton continues to say Trump “would be the end of our country as we know it, and I don’t say that lightly.”) They even made fun board games like “Secret Hitler,” which debuted in 2016 and lists Republican members of the U.S. House and Senate on its website. The game’s unsubtle goal? Kill Hitler before he takes power. “Time to put Trump in a bullseye,” President Biden blurted just days before Trump was shot in Butler, Penn.

With invective like that, Republicans say it is little wonder their candidate has faced three threats on his life in this campaign. America’s lefties hyperventilate claiming Trump plans a Fourth Reich and will end the republic. Rachel Maddow sees the camps coming. Liz Cheney says a vote for Trump may be the last you ever cast. Alexandria Ocasio-Cortez thinks Trump would be the “potential dissolution of democracy” and Trump’s first term was just an “amuse–bouche” (a term which should clue readers in to where the former bartender has been eating as Rome burns).

The ploy isn’t working. The Washington Post recently polled swing state voters on which candidate would better protect Democracy. Turns out, most voters favor Trump to protect the republic.

Auf Wiedersehen, Kamala.
