No blow is too low when President Trump feels compelled to counterpunch his opponents. Democrats are supposed to claim the moral high ground. But each spurious slur and dubious charge they level to justify their impeachment push lowers that high ground.

Consider the Dems’ bogus bigotry charges. False accusations, as everyone knows, hinder the battle against real evil. That’s what Democrats are doing when they falsely accuse Trump of being an anti-Semite.

The claim became a talking point for the #Resistance as the Ukraine investigation has become the focus of their attempts to oust him from office. What’s their evidence? Trump called the Democrats’ impeachment ringleader in the House, Rep. Adam Schiff (D-Calif.), “shifty.”

Rep. Alexandria Ocasio-Cortez said using the word meant that Trump was engaging in “deliberate, atrocious, targeted anti-Semitism.” CNN pundit Peter Beinart said it showed Trump was systematically using “anti-Semitic stereotypes” that might encourage mass killings. The Washington Post’s Dana Milbank tweeted that Trump was trying to portray impeachment as a Jewish project, thus proving the columnist’s previous assertion that the president was making America an “unsafe place for Jews.” Really?

Anti-Semitism has classically framed Jews as deceitful. But Trump never mentioned Schiff’s religion or that of New York’s Rep. Jerry Nadler, the other House committee chairman pushing for impeachment. Other Democrats such as Beto O’Rourke whined about Trump calling the two “savages.” Ironically, that’s a word Yankees fans have embraced as a compliment since manager Aaron Boone’s epic tirade at an umpire in July. In the political context, it’s unquestionably coarse. But now we’re supposed to see it as proof of Jew-hatred?

Name-calling isn’t civil. But Schiff’s continuous over-promising and lying about the Russian collusion hoax shredded his credibility. The same is true of the dishonest manner in which he has promoted the Ukraine charges against Trump. Noting this has nothing to do with his faith. Being Jewish shouldn’t open anyone up to prejudiced attacks. But neither should it shield partisans from harsh criticism.

The anti-Semitism talk is especially rich coming from AOC, who has used language like “concentration camps” to falsely claim Trump’s immigration policies were comparable to those of Nazis and defended her fellow Squad members Reps. Rashida Tlaib and Ilhan Omar when they used overtly anti-Semitic language to besmirch supporters of Israel.

The question is: Why doesn’t the Anti-Defamation League, the group that was once the definitive source on the subject, call out Democrats and their media allies for cheapening the discussion on the topic at a time when a rising tide of anti-Semitism is spreading around the globe?

The answer is that the war on Trump is a higher priority for liberals, including liberals at the ADL, than the fight against hate.

The “shifty” brouhaha isn’t the first effort to smear Republicans for having the chutzpah to bash Jewish Democrats. Liberal media outlets have routinely labeled as anti-Semitic the least criticism of controversial leftist mega-donor George Soros (though some of the attacks Soros faces are unquestionably ­anti-Semitic). And the ADL, which in recent years has shredded nonpartisan principles, has supported this false argument.

Whatever else you may think of Trump, this is one charge that should be rejected out of hand. Trump is the most pro-Israel president we’ve ever had. He had the courage to move the US Embassy to Jerusalem from Tel Aviv. His administration has taken aggressive action against Jew-hatred on college campuses. He has Jewish family members and a cabinet staffed with Jews. But Jewish Democrats have adopted the “Anyone-I-don’t-like-is-Hitler” Twitter meme as their slogan.

If anti-Semitism becomes just one more brickbat to be tossed around in the course of a debate on impeachment, then it loses its real portent as a genuine threat to Jews and democratic societies. Democrats have plenty of arguments to use against Trump. They should stop trying to weaponize and cheapen anti-Semitism for partisan purposes.
