Hillary Clinton just can’t face the fact that Donald Trump’s in the White House and she’s not.

Ten months after her stunning defeat​ in the 2016 presidential race, the Democratic nominee would not rule out challenging the results if investigators turn up solid proof of Russian meddling in the election.

But when asked how she could do that, Clinton was stumped.

“I don’t know if there’s any legal constitutional way to do that. I think you can raise questions,” she told National Public Radio.

Clinton said if she had been elected president and the US intelligence community told her of Russia’s involvement, “I would’ve never stood for it.”

“Even though it might’ve advantaged me, I would’ve said, ‘We’ve got to get to the bottom of this.’ I would’ve set up an independent commission with subpoena power and everything else,” she said in the interview published online Monday.

But later she admitted that there’s no real “mechanism” to dispute the election results.

“Basically I don’t believe there [is a way]. … But people are making those arguments. I just don’t think we have a mechanism,” she said.

​Clinton beat Trump in the popular vote by 3 million votes but lost in the Electoral College — an institution she said should be eliminated.

“Now, I do believe we should abolish the Electoral College, because I was sitting listening to a report on the French election and the French political analyst said, `You know in our country the person with the most votes wins, unlike in yours.’ And I think that’s an anachronism. I’ve said that since 2000​,” she told NPR​.
