No one has ever longed to be president of the United States more than Hillary Clinton. Not even Minnesota Gov. Harold Stassen who - beginning in 1948 - sought the Republican presidential nomination nine times.

Clinton, of course, ran twice. So far.

She’s spent the last three years lumbering around the country - shoot, the world - holding a pity party for herself.

When her 2017 book “What Happened” was published, the BBC listed all of the people and things Clinton fingered for her loss. The blame was spread, the BBC reported, among James Comey, Vladimir Putin, Barack Obama, Bernie Sanders, Jill Stein, sexism and white resentment.

Just last week, in a radio interview with Howard Stern, she blamed Sanders again saying he waited too long to endorse her. 

“He hurt me there's no doubt about it, and I hope he doesn't do it again to whoever gets the nomination. Once is enough," Clinton said, snidely implying that Sanders was not going to be the nominee.

In that interview and others, Clinton said she’s “deluged” with requests to run again.

“I’d have to make up my mind really quickly,” she said on the U.K.’s Graham Norton Show recently, “because it’s moving very fast.” 

Heck, the stars may be aligning for Hillary.

A new Harvard-Harris poll shows that if Clinton entered the race, she’d suddenly become the frontrunner in this field of Democratic fools, edging out Joe Biden by one percentage point.

The poll showed hypothetical Hillary with 21 percent support, Biden with 20, Sanders with 12 and Warren with only 9 percent.

This has to be tantalizing to Clinton. You know, that unbroken glass ceiling and all that. She most certainly doesn’t want Elizabeth Warren breaking it.

The problem for Clinton is that in 2016 she was fresh off a stint as secretary of state. She had a recent resume.

Now? 

She’s bitter. She’s still coughing. And she’s written two lightweight books. The latest, “The Book of Gutsy Women,” doesn’t even include Margaret Thatcher as an example of a historically important female, because , as Clinton told the BBC, Thatcher didn’t do enough for women.

I guess becoming the first female prime minister of Britain wasn’t all that inspirational for girls in her country. And helping to destroy the repressive Soviet Union, unshackling millions of women? No biggie.

This simply shows Hillary Clinton to be a rabid partisan. An unlikable woman who sneered that half of Trump’s supporters were “deplorables.”

When political parlor games began last year, most of us chuckled at the notion of Hillary elbowing her way into the 2020 race.

With this latest poll? Break out the Robitussin. She may be back.
