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

Summary

DonorAtlas, Quiller and BattlegroundAI are progressive-aligned AI startups gaining traction ahead of the 2026 US midterms. Campaign manager Ben Eisenberg reported an 18x return on investment using DonorAtlas in a special election's final weeks, raising $30,000 including $7,000 from cold calls alone. Quiller, an AI copilot for drafting fundraising emails and texts, helped a Bay Area Rapid Transit Board campaign lift its supporter-to-volunteer conversion rate from below 1% to 4%, and is used by digital marketer Mike Nellis for clients ranging from senators to House Democratic leaders. BattlegroundAI, backed by Higher Ground Labs, automatically generates social media and digital ad variants and has been adopted by Kentucky-based Blue Dot Consulting, with one consultant calling it a “super-duper paid intern.” On the Republican side, Push Digital Group is using AI to generate hundreds of ad variants, while OpenAI and Anthropic are themselves becoming political players, raising campaign funds and facing off through affiliated super PACs in New York's 12th Congressional District.
