Forget Joe Biden.

It is feisty Kamala Harris who should be debating President Donald Trump, not Sleepy Joe.

The progressive Democrat and California U.S. senator, who is Biden’s vice-presidential running mate, has more energy in her index finger than the 77-year-old Biden has in his whole body.

Unlike Biden, Harris, 55, is quick and articulate and can put two or more sentences together without forgetting where she is or what she is talking about. She is also tough and mean, and she has been around.

Her mentor was Willie Brown, 85, the wily former mayor of San Francisco and powerful speaker of the California Assembly. He gave Harris her start in politics and supported her for district attorney. She later called him an ”albatross” around her neck.

She showed her meanness when she questioned now-Supreme Court Justice Brett Kavanaugh over phony sexual-assault allegations during his confirmation hearings before the Senate Judiciary Committee.

She was also tough on Biden when she said she believed Tara Reade, the woman who worked in his Senate office and later accused him of sexual assault. Biden denied the charge.

Harris, who is black — of Jamaican and Indian descent — even clobbered Biden on the race issue during a presidential debate.

When she got through attacking Biden for opposing school integration, forced busing and looking up to old segregationists in the U.S. Senate, it looked as though Biden was going to cry.

But Biden recovered, Harris dropped out of the race, and Biden won the nomination. Now that he is running against Trump, he will need all the help he can get, which is why he picked Harris to run with him. She will do to Trump what she did to Biden.

Trump, 74, a man with a mountain of energy,  will wreck a feeble Biden in a one-on-one, 90- minute, stand-up debate, let alone the three that have been scheduled. It will not be pretty.

It is one thing for Biden to attack Trump in an empty Wilmington, Del., gymnasium as he did when announcing Harris, and then taking no questions. It is another thing doing it face-to-face when Trump can counterpunch.

What would be entertaining during these grim days — with nothing worth watching on television, including the news — is a dramatic television matchup between Harris and Trump. The pair had an interesting history before things became nasty between the two.

Trump contributed — and  Harris accepted — $6,000 in two campaign contributions from Trump in 2013 when she was California’s attorney general, along with another $2,000 from Ivanka Trump. Biden gave her nothing.

Those campaign contributions came during a time when Trump gave money to a lot of politicians, Democrats as well as Republicans, and before he ran for president.

Harris reportedly regifted the $6,000 from Trump to a nonprofit immigrant group, rather than return the money to him, when she announced her candidacy for president.

Under this scenario — which will never happen — an energy-depleted Joe Biden would step aside and debate the more even-keeled Vice President Mike Pence, 61, one vice president to another.

Joking aside, Trump quickly sensed that he has something to worry about with Harris on the ticket, which is why he, punching down, attacked her immediately. Presidents normally do not go after vice-presidential candidates.

Trump is acting as though Harris is more of a threat than Biden, and he may be right.

Many people have serious doubts about Biden going the distance in a rough and grueling campaign, given his frailty and his cognitive problems. Turning 78, he would be the oldest president ever elected.

Many people also believe that if he does win, he would not finish his four-year term, let alone run for re-election. Biden has said he would be a transitional president.

So, what you have here is Harris, ostensibly running for vice president, while everybody, especially the dishonest left-wing media, understands that she is really running for president-in-waiting. And the wait may not be that long.

Which is why Democrat media activists like George Stephanopoulos of ABC, The New York Times and the Washington Post are suddenly trying to elect Biden/Harris by presenting Harris as a moderate. The fact is, Harris is a radical progressive to the left even of Bernie Sanders and Elizabeth Warren.

A Trump/Harris debate will not happen, even though it would be boffo television.

Still, Trump needs to be wary of Harris. Joe Biden does, too.
