Former Vice President Joe Biden beat out every other 2020 Democrat by a significant margin in a likability ranking determined by likely Democratic primary voters, according to a new INSIDER poll.

Voters ranked South Bend Mayor Pete Buttigieg, Sen. Bernie Sanders, and Sen. Kamala Harris next highest on the likability ranking.

INSIDER found that male and female voters perceived some candidates' likability very differently. For example, women voters found Biden more likable than male voters did, while women found Sanders less likable than male voters did.

Former Vice President Joe Biden beat out every other 2020 Democrat by a significant margin in a likability ranking determined by Democratic voters who plan to cast their ballots in the 2020 primary, according to a new INSIDER poll.

Once the poll respondents indicated which of the candidates they had heard of, INSIDER asked them to "Please rank the following candidates based on how likable or personable you perceive them to be, with the contender in the first (1) position being the most likable and the contender in the highest-numbered position being the least likable."

Using the results of this question we were able to calculate a "win percentage," where we can divide the times a candidate was ranked higher than a rival by the total number of times they were compared to a rival.

Biden was ranked by respondents as more likable or personable than his opponents 78% of the time. Meanwhile, both South Bend Mayor Pete Buttigieg and Sen. Bernie Sanders were ranked as the more likable candidate 70% of the time.

INSIDER found that male and female voters perceived some candidates' likability very differently. Women voters found Biden more likable than male voters did, while they found Sanders less likable than male voters did.

Sens. Kamala Harris and Elizabeth Warren were ranked next-highest on the likability spectrum. Warren beat out her opponents on the likability measure 63% of the time, while Warren was perceived as more likable 59% of the time.

New York City Mayor Bill de Blasio was ranked the lowest of the nearly two dozen Democratic candidates. Democratic voters said de Blasio was more likable than his opponents just 33% of the time.

A significantly greater percentage of women than men said Harris, Sen. Cory Booker, and Sen. Amy Klobuchar and former Colorado Gov. John Hickenlooper were more likable or personable than their competitors. Meanwhile, a much greater percentage of men than women said Washington Gov. Jay Inslee and entrepreneur Andrew Yang were more likable.

There has been some discussion in recent years about how gender bias influences voters' and the media's perception of a candidate's likability or "authenticity."

In a recent report on the role of gender in the 2016 election, the Center for American Women and Politics at Rutgers University found that female presidential candidates were often held to different likability and ethical standards than their male counterparts. The report highlights how female candidates, including Hillary Clinton and Carly Fiorina, were regularly criticized for not smiling enough and talking too loudly, while male candidates like Donald Trump and Sanders were rarely faulted for their passion or seriousness.

"Research on gender stereotypes reveals that voters may be less likely to expect honesty and ethical behavior from men than from women," the report read. "As a result, it is entirely possible that women candidates might be held to higher standards than men when it comes to honesty and ethics in their pasts and on the campaign trail."

The median female candidate ranked 11th of 23 candidates in INSIDER's poll, while the median male candidate ranked 14th. (Former Georgia gubernatorial candidate Stacey Abrams was included in the survey responses as she's reportedly considering a bid).

INSIDER only notes the split between male and female voters' likability rankings for each candidate when the difference is greater than the margin of error.

SurveyMonkey Audience polls from a national sample balanced by census data of age and gender. Respondents are incentivized to complete surveys through charitable contributions. Generally speaking, digital polling tends to skew toward people with access to the internet. SurveyMonkey Audience doesn't try to weight its sample based on race or income. Total 1,168 respondents collected May 17 to 18, 2019, a margin of error plus or minus 3.08 percentage points with a 95% confidence level.
