They really just can’t stop. Now that the official White House doctor has declared President Donald Trump healthy in mind and body, the liberal attack dogs at the Hollywood funny farm are circling back to their old standby to discredit their political enemies: racism.

On “The Daily Show,” crackpot comedian Trevor Noah responded to Trump’s excellent health evaluation with this little quip:

“No heart problems, no dementia, no dentures… but did you test for racism?”

When Trump’s doctor answered a question on Trump’s less-than-stellar diet, he attributed his continued good health to good genes: “I told the president that if he had a healthier diet over the last 20 years, he’d live to be 200 years old.”

That was just too much hyperbole for Noah’s fragile psyche: “My God! If you think Trump is racist at 71, imagine how racist he’ll be when he’s 200.”

Soooo funny! Eye roll. Noah’s lame effort at comedy fails, not because the charge of racism simply isn’t true, but because it’s an old, worn-out punch line that screams: “Get new material!!”

Here’s the thing. Many Americans simply aren’t falling for it anymore. And they’re certainly not laughing. It’s clear to anyone who is really “woke” that the liberal propaganda army is marching lockstep to discredit and delegitimize Trump, as well as anyone who even remotely supports him.

They tried accusing him of sexual assault, then Russian collusion, then racism, then sexism again, then his mental health, and now back to racism again — because, truth be told, slinging this poo-smeared label is the Democrats’ favorite tactic.

It has been for years, way back to the sixties when Gore Vidal called William Buckley a “crypto-nazi.” I wrote about this during the election, explaining how the Left has a shameless history of calling Republicans racists: “While the degree of conflict changes, the essence of it doesn’t. Neither do the alarmist and exaggerated depictions of racism on the Right.”

Trump isn’t anything new; he’s just the most recent in a long line of Republican targets.

Noah is just repeating the same old line. It’s boring, it’s untrue, it’s unoriginal, and it’s not funny. It’s a tool to manipulate the clapping seals who mindlessly absorb his comedic propaganda. The rest of us aren’t so stupid or fearful of lefty stigmatizing.

Note to Noah and his liberal cohorts: This is how Trump got elected, and if you keep it up, you can be sure he’ll be elected again.
