Remember when Jimmy Carter published a whiny, self-serving book about his political downfall called “What Happened”? Remember when Mike Dukakis pushed filmmakers to do a four-hour fan documentary about himself? Remember when George H.W. Bush mocked Bill Clinton at the Grammys? Yeah, me neither.

Previous losing presidential candidates had the dignity to back off and bow out of politics. Yet here is Hillary Rodham Clinton, the recurrent canker sore on America’s butt, which is politics. This week she again tried to reintroduce herself to us all as anything but what she is, which is a sore loser. Her attempts to scramble back into the political spotlight after the American people booed her off the stage have been so pathetic that she resorted to calling Army major and Hawaii Congresswoman Tulsi Gabbard “a Russian asset” — a loony insult that this week got Clinton socked with a lawsuit for defamation.

How funny would it be if Hillary were forced to transfer a chunk of her filthy fortune to Tulsi?

This week, to promote the upcoming four-hour Sundance/Hulu documentary “Hillary,” a project launched by Hillary herself, Clinton gave an interview to The Hollywood Reporter in which she turned on one of her party’s two front-runners for the presidential race, proving yet again that God sent Hillary Rodham Clinton to earth as a beautiful gift to the Republican Party.

What could be more delightful than to hear Rotten Rodham pelt Bernie Sanders with her sour grapes?

“He was in Congress for years. He had one senator support him. Nobody likes him, nobody wants to work with him, he got nothing done,” Clinton said in the film, sticking by the remarks in the interview.

“He was a career politician. It’s all just baloney and I feel so bad that people got sucked into it.”

Career politician? Sanders drives a 2010 Chevy subcompact. The car he drove in the 1980s, when he was mayor of Burlington, was so pathetic it was once nearly ticketed by a meter maid who, when she saw it parked in the space reserved for the mayor, couldn’t believe any mayor would ever drive such a thing.

Hillary Clinton is far worse than a “career politician” — she’s a kleptocrat who got rich selling access to herself to lobbyists and foreigners. Bernie may be barmy but he is not for sale and he never made any money to speak of until his book “Our Revolution” became a hit in 2016.

As for the “nobody likes him,” honey, that’s like your husband calling Mitt Romney a skirt chaser.

In the interview Hillary wouldn’t even commit to backing Bernie in the general election, should he be the Democrats’ pick.

What the fudge, Madam Pantsuit? Haven’t you been saying President Trump is a dire threat to democracy?

Yet when asked whether she’d support Sanders over Trump, she said, “I’m not going to go there yet. We’re still in a very vigorous primary season,” then hinted that she might withhold her endorsement because of the Bernie Bros.

Some of Bernie’s Twitter trolls are such a nuisance that she’s not sure she can endorse Sanders over Trump?

If there is any doubt whatsoever in her mind about whether to back Sanders after he becomes the nominee, this reduces to rubble any future statements she may make that Trump is uniquely unfit or uniquely dangerous for office. Her petty feud with Team Sanders makes it clear that her differences with Trump are equally petty, and derived from the same source: her embarrassment about how badly she did against these two long-shot outsiders.

So keep talking, Hillary.

You’re the Republican Party’s most valuable spokesperson.
