  “But what this points to is a Democratic margin in the House popular vote of 13 points, which is considerably higher than what the current congressional ballot... is pointing to. That's around D+8.”

  Shapiro argued the midterm environment was breaking toward Republicans: he predicted the GOP would win the national generic/House vote by five to seven points, said Ted Budd and Brian Kemp would cruise in North Carolina and Georgia, expected strong Republican gubernatorial candidates in Arizona and Georgia to pull Blake Masters and Herschel Walker to victory, said Joe Lombardo would win Nevada's governorship, and made Lee Zeldin beating Kathy Hochul in New York his 'sleeper pick.'

• G. Elliott MorrisHouse Popular Vote MarginsPending
  Morris says both the polls and his model's non-poll "fundamentals" point to a strongly Democratic year, with his FiftyPlusOne House popular-vote forecast at roughly D+9. He also argues Henry Olsen's seat model understates Democrats by about 10 seats relative to Olsen's projected Democratic majority of 225–232.
• Daniel DonnerHouse Popular Vote MarginsPending
  Analyzing a long-run relationship between midterm primary turnout and the House popular vote, he concludes that 2026 primary turnout points to Democrats winning the national House vote by about 13 points, and says either that or the generic-ballot's smaller edge would be enough for Democrats to retake the House.
