Our Story

FiftyOne Percent began in 2010 to bring a new, personalized approach to campaign management. We understand every campaign and every candidate is different. That’s why we focus on using data and close collaboration with our clients to develop a plan that will get them the votes they need to win while staying true to their values.

This approach has already succeeded in a variety of different contexts, from helping Cory Booker’s successful elections to the United States Senate, to guiding Representative Bonnie Watson-Coleman to victory in a primary that few expected her to win, to giving longshot candidate Andrew Zwicker the tools and advice he needed to defeat an opponent who outspent him three-to-one. FiftyOne Percent is not afraid to take on the toughest fights.

FiftyOne Percent was founded on the idea that every campaign is unique and that candidates win when they feel passionate about and invested in their races. We know that there is not one right way to run a campaign, so we focus on working with our clients and using our sophisticated data analysis and behavioral modeling to develop a plan specifically for them that will get the votes they need to win.
