The latest public opinion poll on the Democrats running for president in 2020 shows former Vice President Joe Biden with a double-digit lead (he is at 33%) over the nearest challenger, U.S. Sen. Bernie Sanders (with 14%).

Every other candidate — including U.S. Rep. Tulsi Gabbard of Hawaii — is polling in single digits. And a large number surveyed — 19 percent — are undecided.

The Hill-HarrisX poll was released Wednesday. While anything can happen to shake up the race, four other polls this month show roughly the same numbers for the candidates, who now number 24.

All five polls (the others are from Quinnipiac, Morning Consult, FOX News and Emerson) have Gabbard at just 1%, just ahead of businessman Andrew Yang and just behind U.S. Sen. Amy Klobuchar.

Since she declared her candidacy in January, Gabbard has barely registered in the polls, according to data tracked by Real Clear Politics.

Things may change when the first televised debates are held in Miami on June 26 and 27. Only 20 candidates may qualify (Gabbard is one of them), with 10 appearing each night.
