Democratic candidates in the 2026 midterms face direct comparisons to Kamala Harris's 2024 presidential vote share in their states, with markets resolving on certified general-election results for Senate and governor races on November 3. Recent Times/Siena and Marist polls indicate Democratic nominees holding or gaining ground in several Trump-won states, including Alaska, Iowa, Ohio, and Texas, which could lift some candidates above Harris's prior margins in those jurisdictions. In contrast, tighter or weaker polling for figures such as Peggy Flanagan in Minnesota and Chris Pappas in New Hampshire relative to 2024 baselines raises the prospect of underperformance in more Democratic-leaning states. Harris's own midterm campaigning in Michigan, Nevada, and Georgia has coincided with broader party momentum in prediction markets favoring Democratic Senate and House gains, though final vote shares will depend on turnout patterns and any late shifts before certification.
