A new Echelon Insights survey of registered voters conducted Aug. 14-18 shows former Vice President Kamala Harris maintaining a modest lead in the 2028 Democratic presidential primary with 26% support, unchanged from the firm’s April polling. California Governor Gavin Newsom continues to gain ground, climbing three points to 13% and tripling his share since the spring. Transportation Secretary Pete Buttigieg follows at 11%, while Rep. Alexandria Ocasio-Cortez stands at 6% and Sen. Cory Booker slips to 5%. Rising newcomer Rep. Jasmine Crockett registers 3%, up two points. Harris’ advantage widens among Black Democratic voters, where she commands 35% support compared with 11% for Crockett and 8% for Newsom, according to the poll’s 96-respondent subsample. Buttigieg records no measurable backing in that demographic, underscoring the former vice president’s continued strength with a key party constituency even as overall enthusiasm for the field remains diffuse. On the Republican side, Ohio Senator J.D. Vance leads the pack with 43%, one point below his previous showing. Robert F. Kennedy Jr.—who formally switched parties earlier this year—surges into second place at 9%, level with former Florida Governor Ron DeSantis. Senator Marco Rubio draws 6%, followed by former U.N. Ambassador Nikki Haley at 4%, while other potential contenders poll in the low single digits. The poll highlights the fluid nature of both 2028 nomination contests, with front-runners holding only pluralities and sizeable blocs of voters still undecided more than two years before the Iowa caucuses.
