Recent polling data from Overton Insights and Targoz conducted between June 23 and 26, 2025, reveal evolving dynamics in both the 2024 U.S. presidential rematch and the 2028 Democratic primary race. In a hypothetical 2024 rematch, former President Donald Trump leads with 46% support, while incumbent Vice President Kamala Harris holds 43%, with 11% favoring other candidates. Polls for the 2028 Democratic primary show varying levels of support depending on the scenario. Without Harris in the race, Pete Buttigieg, Tim Walz, and Gavin Newsom each garner 15%, followed by Alexandria Ocasio-Cortez at 11%, Josh Shapiro at 8%, Cory Booker and Gretchen Whitmer at 7% each, Wes Moore and Stephen A. Smith at 4% each. When Harris is included, she leads with 38% to 45% in different polls, followed by Buttigieg (11%), Newsom (10%), and Ocasio-Cortez (7%). Another poll presents a three-way contest with Harris commanding 67%, Ocasio-Cortez 20%, and Charles Barkley 6%. Additionally, a head-to-head 2028 poll shows Harris at 45% against J.D. Vance's 42%. Commentary suggests Harris appears stronger in the 2028 Democratic primary than in the California gubernatorial race. These polls indicate a competitive landscape ahead of the 2028 election, with Harris maintaining a leading position among Democratic contenders and Trump holding a narrow advantage in a potential 2024 rematch.
