The split screens said it all, even when the mics were muted.

Trump was angry, unhinged and afraid to look Kamala Harris in the eye.

Harris was in command all night.

It was the most dominating performance in the history of presidential debates since JFK won the very first one in 1960.

It was the first time a debate opponent, Democrat or Republican, dominated Trump.

She took control when she strode onto stage, walked into Trump’s space, forced him to shake her hand and told him how to pronounce her name: “Kamala Harris.”

She baited his ego about his rally-crowd sizes, and he never recovered his footing.

He raved about how much Hungarian dictator Viktor Orban loves him, called himself a “leader in fertilization,” ducked responsibility for January 6 and repeated the bizarre claim, “They’re eating the dogs, they’re eating the cats, they’re eating the pets.”

That bid for childless cat ladies flopped, as Taylor Swift endorsed Harris after the debate.

Harris’ best moment came when she turned the page and turned to the future: “Clearly, I am not Joe Biden, and certainly not Donald Trump, and what I do offer is a new generation of leadership for our country.”

JFK would have approved.

Trump lied throughout the debate, of course. But he told a lie about abortion that Americans could fact-check themselves: that “everybody” wanted to get rid of Roe v Wade. Millions of Americans immediately thought, “No, we didn’t.”

You knew Trump lost when he went into the spin room himself. You know he lost when MAGA world complains about the moderators and threatens to boycott ABC.

Like 1960, this will be a close election. Millions of Americans buy Trump’s dark view of the future.

But millions more want a brighter way forward.

Last night, Harris took a giant step there.
