A CNN poll released Wednesday shows former Vice President Joe Biden leading the pack by the widest margin he’s had since April.

Biden has 34 percent of the vote, followed by Sens. Elizabeth Warren (D-MA) and Bernie Sanders (I-VT) at 19 and 16 percent respectively.

According to the poll, Biden has seen support rise from moderate and conservative Democrats, racial minorities and older voters.

The poll also gives both former Rep. Beto O’Rourke (D-TX) and Sen. Amy Klobuchar (D-MN) a qualifying national poll needed to make the stage for the November debate.

The poll was conducted with a sample size of 1,003 adults and has a margin of error of +/- 3.7 percentage points.
