Democratic primary voters perceive former US Senator and Vice President Joe Biden to be far more experienced than the rest of the 2020 presidential primary field, new INSIDER polling found.

To capture how every candidate's experience is perceived in a single number, in a recent survey we asked respondents to rank the 2020 candidates they knew of by how experienced they saw the candidate to be.

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 won 90% of match-ups, meaning that when he was ranked, he was ranked higher than other ranked candidates 90% of the time.

To capture how every candidate's experience is perceived in a single number, we asked respondents to rank the 2020 candidates they knew of by how experienced they saw the candidate to be.

Once the poll respondents indicated which of the candidates they had heard of, INSIDER asked them: "Based on what you know about candidates history of public service and experience with government, can you rank the following people based on how prepared they are for the rigors of the presidency?"

Biden, who was President Barack Obama's vice president for eight years following a 36-year-long career in the US Senate, won 90% of match-ups, meaning that when ranked, he was ranked higher than 90% of other ranked candidates.

Meanwhile, both Sen. Bernie Sanders, the highest-ranked senator, and Sen. Elizabeth Warren were ranked as the more experienced candidate in more than 65% of their matchups.

The survey didn't reveal any clear gender-based trends in how respondents viewed male compared to female candidates.

While male respondents ranked Sen. Kamala Harris and Rep. Tulsi Gabbard as being more experienced than female respondents, the opposite was true for Sens. Elizabeth Warren and Amy Klobuchar, for whom women's perception of their experience was higher than men's.

And for some male candidates, such as Rep. Eric Swalwell, the highest-ranked member of the House, Rep. Tim Ryan and former HUD Secretary Julian Castro, female respondents' perception of their experience was higher than male respondents' perceptions by significant margins.

In an unlikely twist, Swalwell still ranked higher than Sen. Michael Bennet and Gov. Steve Bullock, the lowest-ranked senators and governors. Here's how our poll respondents ranked the candidates:
