The chart above reflects the results of the new Quinnipiac University Poll -- done between June 28th and July 1st of a national sample of 554 Democrats and Leaners, with a 5 point margin of error.
The poll, like others done after the Democratic debates, shows the debates really helped Kamala Harris. She has vaulted into second place, only 2 points behind Biden. Warren and Sanders are in third and fourth place. No other candidate is even close to double figures.
