A new national Democrat primary poll released Tuesday shows former Vice President Joe Biden with a roaring lead over his Democrat socialist rival Bernie Sanders.

Quinnipiac reported polling results showing that Biden is now at 38 percent support from Democrat and Democrat-leaning Americans, while Sanders only has 11 points.

Sen. Elizabeth Warren is gaining in popularity, sitting in second place with 12 percent, while Mayor Pete Buttigieg is now at ten percent. Sen. Kamala Harris rounds out the top five with eight percent.

A big part of Biden’s appeal is his ability to win. Fifty-six percent of Democrats said that Biden has the best chance to beat President Donald Trump, while only 12 percent said the same about Sanders.

Forty-seven percent of Democrats say that Biden would be the “best leader,” while only 11 percent said the same about Sanders.

The telephone survey was conducted from April 26–29 including 1,044 self-identified registered voters – 419 of which included Democratic or Democratic-leaning voters with a margin of error of +/- 5.6 percentage points.
