Joe Biden holds a substantial lead over fellow Democratic presidential candidates Sen. Elizabeth Warren and Sen. Bernie Sanders in two national polls released Wednesday.

Voters gave the former vice president 32 percent support in a Quinnipiac survey, compared to 19 percent for Warren and 15 percent for Sanders.

Biden also got 32 percent support — 18 percentage points higher than Warren and 20 points more than Sanders — in a USA Today/Suffolk University poll.

The other Democratic hopefuls trailed far behind the trio.

In the Quinnipiac poll, Sen. Kamala Harris won 7 percent support, Mayor Pete Buttigieg got 5 percent and businessman Andrew Yang gathered 3 percent.

The remainder of the candidates — including Mayor Bill de Blasio and Sen. Kirsten Gillibrand — got 1 percent or less.

Buttigieg and Harris tied at 6 percent in the USA Today survey followed by Yang at 3 percent and former Rep. Beto O’Rourke and Sen. Cory Booker locked at 2 percent.

The rest were 1 percent or lower.

The polls came out as the Democratic candidates face a midnight Wednesday deadline to qualify for next month’s debate.

As of Wednesday morning, the former sprawling field of candidates had been winnowed to 10.

Sen. Amy Klobuchar and former Housing and Urban Development Secretary Julian Castro have made the cut along with Biden, Warren, Sanders, Harris, Buttigieg, Booker, O’Rourke and Yang.

To qualify, candidates have to have 130,000 unique donors and poll at 2 percent in four national surveys.

The Quinnipiac poll surveyed 1,422 voters nationwide between Aug. 21 and Aug. 26. It has a plus/minus 3.1 percentage-point margin of error.

The USA Today poll surveyed 424 registered voters between Aug. 20 and Aug. 25. It has a plus/minus 4.96 percentage-point margin of error.
