A Democratic megadonor told Colin Powell that Hillary Clinton “HATES” President Obama for beating her for the 2008 nomination, and she dismissively referred to him as “that man,” according to emails hacked from the general’s account.

Corporate financier Jeffrey Leeds depicted Clinton as a sore loser set on revenge in the ­emails, which were obtained by The Intercept, and claimed Clinton is terrified she might lose again.

“I think Hillary can’t believe she might not make it,” Leeds wrote to Powell in March 2015. “It’s the one prize she wants. She has everything else.”

Leeds went on to say that the 2008 Democratic primary left Clinton and Obama bitter rivals.

“And she HATES that the President (‘that man,’ as the Clintons call him) kicked her ass in 2008,” he wrote. “She can’t believe it or accept it.”

Leeds also wrote that Hillary’s State Department email scandal might wreck her campaign — and that Obama wouldn’t mind watching her burn for it.

“No one likes her and the criminal thing ain’t over,” Leeds wrote in another email.

“I don’t think the president would weep if she found herself in real legal trouble. She’ll pummel his legacy if she gets a chance and he knows it.”

As for Powell, the statesman lamented that Clinton’s camp was blaming him for her email problems, even claiming he threw a “tantrum” during a party in the Hamptons to get Team Hillary off his back.

“HRC could have killed this two years ago by merely telling everyone honestly what she had done and not tie me to it,” Powell said in an email last month.

“I told her staff three times not to try that gambit. I had to throw a mini tantrum at a Hampton’s party to get their attention. She keeps tripping into these ‘character’ minefields.”

Powell also said he has doubts about Clinton’s health.

“She doesn’t look good,” Powell said in an email. “She is working herself to death.”

The Intercept said the ­emails were leaked by a website connected to Guccifer 2.0, the notorious hacker who allegedly has ties to Russia and has released thousands of Democratic National Committee documents.

Powell insisted that his use of email when he was President George W. Bush’s secretary of state was different than Clinton’s, and she inevitably messes everything up.

“They are going to dick up the legitimate and necessary use of emails with friggin record rules. I saw email more like a telephone than a cable machine,” he wrote.

“As long as the stuff is unclassified. I had a secure State.gov machine. Everything HRC touches she kind of screws up with hubris.”

Clinton sought Powell’s advice during a dinner in 2009, and Powell has regretted giving it ever since.

“I warned her staff three times over the past two years not to try to connect it to me,” Powell wrote. “I am not sure HRC even knew or understood what was going on in the basement.”
