Dramatic CNN poll shakes up the Democratic primary race, with bad news for Joe Biden

A stunning new poll from CNN shows former Vice President Joe Biden narrowly hanging on to a slim lead and two new competitors for the top spot after a contentious set of debates.

Biden loses 10 percentage points of support from 32 percent in May to 22 percent in this latest poll.

On the other hand, support has rocketed up for Sen. Kamala Harris (D-Calif.), who comes within 5 percentage points of the front-runner with 17 percent. She had only 8 percent of support in May.

Another big winner is Sen. Elizabeth Warren (D-Mass.) who has also doubled her support from May, when she had 7 percent of support, until this recent poll where she comes in at 15 percent.

Both Sen. Bernie Sanders (I-Vt.) and South Bend, Indiana, Mayor Pete Buttigieg have lost support, with a 4-point loss for Sanders and a 1-point loss for Buttigieg.

The poll follows along with the pundit consensus about the pair of Democratic debates that saw Harris challenge Biden with a dramatic rhetorical attack on his position on forced government school busing.

A Morning Consult/FiveThirtyEight poll released on Friday found a similar 10-point drop for Biden among likely Democratic voters.

CNN contributor Van Jones bemoaned the performance of the Democrats at the debates, which he said were bad for Democrats and especially bad for Biden.

President Donald Trump had a one word assessment of the first night of the debates: "BORING!"
