Another presidential poll, another dose of bad news for Elizabeth Warren.

Our senior senator and declared presidential candidate found herself trailing two other well-known but undeclared Democrats — as well as an upstart U.S. senator from California — in a UMass poll of likely New Hampshire Democratic primary voters.

Former Vice President Joe Biden led the list of declared and potential candidates in New Hampshire at 28 percent, followed by Vermont Sen. Bernie Sanders (20 percent) and Sen. Kamala Harris (14). Sanders has since announced his intention to again run for president, but had not at the time of this Feb. 7-15 survey.

All Warren could muster, despite officially announcing her candidacy in Lawrence — in the shadow of the Granite State — was a disappointing 9 percent. No one else registered more than 6 percent.

Warren did score the highest in one poll category — most polarizing. Twenty-six percent of those surveyed indicated they would not vote for her if she became the party’s nominee, the highest negative the field.

Warren’s poll numbers follow a discouraging pattern.

In a December University of Massachusetts/YouGov survey of probable Democratic presidential candidates, Warren again trailed both Biden and Sanders, while in a Suffolk University Political Research Center/Boston Globe poll of likely Massachusetts voters released in September, 58 percent didn’t approve of Warren running for president — a result that shocked veteran pollster David Paleologos,

Warren probably can take some comfort in the relatively small sample size of this latest poll, 337, and its relatively high margin of error, 6.8 percent. However, it did reinforce the obstacles she continues to face — both politically and personally.

Biden topped the field in New Hampshire primary survey because those polled gave him the best chance of defeating President Trump in 2020. We’d say another of the 76-year-old Delaware Democrat’s strengths is his ability to project a personal warmth that Warren sorely lacks. While a liberal, he’s also a political realist, willing to compromise, which would play well in some of those battleground states that went Trump’s way in 2016.

Warren must hope that Biden decides to stay out of the race, but she still must overcome the populist popularity of the 77-year-old Sanders; that will be tested almost immediately during primary season in New Hampshire.

Most pundits agree Warren must win there to prove she’s a viable national candidate. She won’t enjoy a home advantage, since both she and Sanders come from neighboring states. And she can’t afford a repeat of Hillary Clinton’s performance, whom Sanders trounced by more than 20 points in 2016.

And while Warren’s campaign account — listed as just over $11 million in her latest financial filing — would be the envy of most presidential wannabes, she’ll have a hard time matching Sanders’ fundraising prowess.

According to the State House News Service, Sanders announced that he had raised an astronomical $5.9 million in donations in the 24 hours after his formal announcement, which reflects the continued strength of a political network he built during his populist 2016 campaign.

That Granite State primary test may be still a year away, but if future polls continue to reinforce Warren’s likability deficit disorder, her campaign may “Feel the Bern” in the snows of New Hampshire, and simply melt away.
