1. Our lists: Explanation
2. Super-priority list - October 2025
3. Supplementary list - October 2025
The aim of this website is to identify the candidates for whom your donations or volunteering are likely to make the greatest difference in helping Democrats gain control of the House in 2026, and gain control of the Senate (or at least build Dem numbers in that chamber) in 2026.
1. Our lists: Explanation
Our lists in sections 2 and 3 are based on our conversations with experts in DC who have the best overview of every race in the nation. These are the candidates in the closest races; expected to be within 1 or 2 percentage points. We exclude candidates when they are in competitive Democratic primaries, or their Republican opponent is not yet known and may affect whether the race will be close, or there is a more-than-remote chance of redistricting in the state which may affect whether a House race will be close. For example, this month California, North Carolina and Ohio candidates are not included in these lists because redistricting may affect the races.
The hyperlink on each candidate’s name links to their campaign website, where you can learn about the candidate, and donate or volunteer if you wish.
