Case Study: Democrats Abroad achieves a 300% increase in overseas voter turnout with CallHub

How Democrats Abroad Drove a 300% increase in overseas voter turnout with phone calls

Democrats Abroad, the official Democratic Party arm for over 3 million potential U.S. overseas voters, faced a complex absentee-voting landscape, missing or outdated voter records, and a manual, country‑limited phone‑banking process that hampered turnout efforts. To scale for the 2018 midterms they moved their phone‑banking operations into CallHub’s centralized calling platform and integrated it with their NationBuilder membership database to reach more than 150,000 members across 190 countries.

Using CallHub’s automated dialing, personalization (Tags, Custom Fields, Surveys) and CRM integration, Democrats Abroad enabled volunteers worldwide to make quality, data‑driven conversations and feed real‑time updates into NationBuilder. The result: calls per hour doubled, over 90% of conversations were positive, 1,124 volunteers in 57 countries reached voters in 190 countries, and overseas turnout rose on average 3x (up to 8x in some states), helping drive roughly 50–70% of U.S. overseas voter turnout in 2018 — achievements enabled by CallHub.
