Signal AI 2026 Midterm Campaign Tools: DonorAtlas, Quiller, BattlegroundAI Surge

Summary

DonorAtlas, Quiller and BattlegroundAI are progressive-leaning AI startups gaining ground ahead of the 2026 US midterms. Campaign manager Ben Eisenberg said DonorAtlas delivered an 18-times return on investment in the final stretch of a special election, helping raise $30,000, including $7,000 from cold calls alone. Quiller, an AI copilot that drafts fundraising emails and texts, lifted a Bay Area Rapid Transit Board campaign's supporter-to-volunteer conversion rate from under 1% to 4%, and digital marketer Mike Nellis uses it for clients ranging from senators to House Democratic leaders. BattlegroundAI, backed by Higher Ground Labs, automatically generates social media and ad variants and has been adopted by Kentucky's Blue Dot Consulting, with one consultant calling it a super-duper paid intern. On the Republican side Push Digital Group is generating hundreds of ad variants with AI, while OpenAI and Anthropic have themselves become political actors raising campaign money and clashing through affiliated super PACs in New York's 12th District.
