Joe Biden’s got some timing: As President Trump traveled to Dayton and El Paso to console victims, and just days after he called for unity against racism, the ex-veep accused him of doing the opposite.

A president’s words can “unleash the deepest, darkest forces in the nation,” and that, Biden insisted Wednesday, is what Trump “has chosen to do.” The 2020 Dem wannabe claimed the president “encourages and emboldens” white supremacy and has “poured fuel on the fire” of hate crimes.

Sure, Biden’s in a tough fight for his party’s nomination. But doesn’t he care at all about healing and uniting the nation after last weekend’s devastating massacres?

How is painting Trump as just short of Adolf Hitler and stirring up fiery resentment toward him going to calm the public, heal the wounds and bring folks together? Who is pouring fuel on the fire?

On Monday, by contrast, Trump called on the nation, to condemn, in one voice, “racism, bigotry and white supremacy.”

“Now is the time to set destructive partisanship aside,” he said, “and find the courage to answer hatred with unity, devotion and love.” Even a front-page New York Times headline admitted “TRUMP URGES UNITY VS. RACISM” (until haters threatened to boycott, prompting a rewrite).

Trump explicitly pleaded with the nation to “defeat” racism and white supremacy, labeling them “sinister ideologies.” Such hatred, he warned, “warps the mind, ravages the heart and devours the soul.”

Now, you may think that’s not fanning flames; but Biden (who apparently can read minds) claims Trump didn’t mean it. The prez, he says, “can barely bring himself to use the words ‘white supremacy.’ ” (After which Team Trump tweeted numerous clips of him blasting the KKK, neo-Nazis and — you guessed it — white supremacy.)

Biden isn’t the first pol to twist words or falsely accuse a rival. But to do so specifically to inflame and divide, so soon after a national tragedy and even as the president strived to offer comfort — well, that’s truly a new low.
