Overview
- A national Center Square Voters' Voice Poll, conducted June 4–6, 2026, found Harris at 27% support, Gavin Newsom at 14% and Pete Buttigieg near 11% among 1,224 Democrats and left‑leaning independents.
- Both Harris and Newsom have slipped from earlier Center Square tracking, with Harris falling from 33% in October and Newsom from 21%, signaling shifting short‑term support within the party.
- The poll used an opt‑in online panel and text‑to‑web outreach, which Noble Predictive Insights collected, a nonprobability method that limits margin‑of‑error interpretation and direct comparison with probability‑based surveys.
- Harris showed especially strong backing from Black voters and those ages 18–29 while Newsom led older voters and respondents with postgraduate degrees, revealing sharp demographic divides in early preferences.
- Coverage notes a contrasting Emerson College poll released in late May that put Harris near 10%, and the gap between polls combined with a 17% undecided share means the race remains open and could shift with endorsements, campaigning, or fundraising gains.
