AINews Summary

New Hampshire remains a key open-seat Senate race, with Republicans actively targeting it and both Chris Pappas and John Sununu in the field. Broader coverage says Democrats need to defend seats like New Hampshire while also making gains elsewhere to win Senate control. Maine’s unsettled Democratic primary is adding to the wider uncertainty around the 2026 map. The New Hampshire race remains competitive, with the open seat keeping both parties in play. Broader Democratic uncertainty in other Senate contests could slightly help Republicans if it weakens the party’s overall control path.
