Post-Debate Poll Shows Harris Big Winner

The post-debate poll of the Democratic Primary competition shows Joe Biden still on top with 28% support. He is followed by Bernie Sanders at 14%, Kamala Harris at 11%, and Elizabeth Warren at 8%. Fifteen percent (15%) say they are not sure (see full topline results for all candidates).

No other candidate reached the 5% level of support.

Compared to our pre-debate survey, Harris gained five points and Sanders lost 3. Biden and Warren each lost a point.

These results are based upon a poll of 909 Registered Democrats and Democratic Leaning Independents.  This survey was conducted from Friday, June 28 at 7 p.m. Eastern until Sunday, June 30 at noon eastern.

  • For the final wave of the survey (Saturday-Sunday), Biden was at 32% while Sanders and Harris were tied at 13% each. Harris gained ground on each of the last three polling days. Sanders dropped each day.
  • Biden fell to 25% on the Friday-Saturday polling and then bounced back on the next polling day.
  • Warren remained steady throughout.

Among all other candidates, no one gained or lost more than a point. The number saying they would not vote grew from 1% to 3%.

In addition to our public opinion polling, measures the Social Media Support for each Democratic candidate.  Support is measured both in terms of volume of chatter and how positive or negative the chatter is about a particular candidate. New numbers are released by each morning at 4:30 a.m. Eastern.
