Joe Biden may be losing momentum in the 2020 Democratic presidential contest as a new poll shows the former vice president declining in support — and Sens. Kamala Harris and Elizabeth Warren gaining ground.

Biden received 22% of support from registered Democrats in a CNN poll released on Monday, a decline in 10 percentage points from the last poll of its kind conducted in May.

That left the one-time Delaware senator just five points above California senator Harris, who had a combative exchange with Biden during last week’s debate in Miami.

Harris had doubled her support in the June survey — jumping from 8% to 17%.

Massachusetts senator Warren also got a boost in the polls, surging from 7% to 15%.

Another notable change in the Democratic contest was Vermont Sen. Bernie Sanders, who slipped four percentage points.

The 2016 primary challenger to Hillary Clinton slid from 18% support to just 14% in the survey.

The poll was conducted after the first round of Democratic debates in Miami last week.
