Case Study: Manuel Natal Albelo achieves massive voter engagement and mobilizes thousands of volunteers with NationBuilder

Manuel Natal Albelo engages scores of new voters in San Juan mayoral campaign

Manuel Natal Albelo, a progressive insurgent running for San Juan mayor with the newly formed Citizens’ Victory Movement, faced a limited budget, no established party infrastructure and a pandemic that eliminated in‑person organizing. To rapidly build a reliable voter file, identify supporters, and manage volunteers and digital outreach, his team adopted NationBuilder’s integrated CRM, texting and volunteer‑management tools.

Using NationBuilder (with partner integrations like CallHub) the campaign cut lists quickly, scaled texting and phone‑banking, mapped field operations and ran workflows to train and assign thousands of volunteers. NationBuilder helped mobilize 3,379 volunteers, enabled 38,672 one‑to‑one contacts and captured 15,159 new supporters—delivering a near‑upset on election night, creating a clean database for future cycles, and allowing the team to manage a rapid volunteer surge in the post‑election period.
