It wasn’t that long ago that the 2020 presidential campaign of Sen. Elizabeth Warren (D-Mass.) was at the point of solidifying frontrunner status.

Her radical feminism and economic socialism were considered the right mixture for the far-Left Democrat primary voter base.

But politics is a fickle mistress — and a star that was once a classic red giant can turn into a white dwarf within the space of several weeks.

So it is with Warren, as her fundraising numbers have dropped 30 percent in the fourth quarter of the year, compared to the last quarter.

That third quarter total was $24.6 million.

Sen. Bernie Sanders (I-Vt.) led the third quarter with $25 million. (The fourth quarter of the year ends on January 31.)

Warren admitted as much to supporters on Friday in an email plea for funds: “So far this quarter, we’ve raised a little over $17 million. That’s a good chunk behind where we were at this time last quarter,” the missive noted.

Her comparatively small haul is the product of swings and misses during the debate season and in messaging.

Warren’s recent attack on Mayor Pete Buttigieg of South Bend, Indiana — another Democratic contender and the beneficiary of Warren’s missteps — backfired badly.

She accused him, during the last Democrat primary debate — in Los Angeles on December 19 — of financing his campaign by holding fundraisers “in wine caves” and relying on high-dollar donors for much of his donations.

It was soon revealed that Warren herself had thrown campaign events in similar venues — and until just before she went after Buttigieg for it, had solicited the same type of high-roller donor cash.

That mistake helped Buttigieg shoot to frontrunner status in Iowa at her expense.

This is an example of amazingly shoddy staff work on the part of her campaign team. Warren’s media handlers, who no doubt wrote all her attack points, apparently had such little knowledge of their own campaign that they led Warren into a minefield by briefing her to hit Buttigieg with that message.

That is on top of her disastrous past attempts to appear “working class,” as in the unintentionally comic campaign video of Warren making a bizarre effort to drink a bottle of beer at home in front of millions of people, potentially.

Combine those factors with the widely held perception that she is too far-Left to win — and that President Donald Trump would love to run against her — and you have the recipe for a sinking campaign.

Sure, there’s still time to right the Warren ship.

But if action is not taken soon, then another Democrat White House hopeful may fall by the wayside — well ahead of the Iowa caucuses in early February.
