The nation’s leading ballot measure campaign firm

Winner & Mandabach Campaigns is a national, full-service ballot measure campaign and issue management firm. Our specialties include campaigns for and against initiatives, referenda, constitutional amendments, and bond measures, as well as public policy-oriented issue management campaigns.

W&M oversees all aspects of ballot measure campaigns, including strategic planning, public opinion research, advertising, direct mail, digital/social media, phones/text messaging, earned media, and grassroots/outreach activities.

The firm has managed and consulted on over 200 statewide and local ballot initiative campaigns in 31 states — more than any other firm in the nation — while maintaining a 90% win rate.

At Winner & Mandabach, we’re proud of our pioneering work in the ballot measure field. From the beginning, we’ve recognized that the dynamics of ballot measure and issue campaigns differ significantly from candidate campaigns. Over the course of more than 200 campaigns, our firm has developed and refined winning methodologies that address those differences.

Winning YES & NO Campaigns

Since 1990, the firm has won over 70 YES ballot measure votes, which are historically more difficult to win than NO votes. W&M is the only firm in the country that has passed such a large number of ballot measures.

Broad Issue Experience

The firm has directed campaigns and managed public policy issues for a wide variety of clients of every size and sector, including energy, gaming, technology, taxation, health care, food and beverages, agriculture, biotechnology, local government control, deregulation and municipalization of utilities, education, sports, transportation, banking, civil rights, insurance, mining, land use, packaging, telecommunications, and water and the environment.

Innovative Technology

W&M has been at the forefront of introducing new technologies to the ballot issue measure space. The firm was the first in the ballot measure field to deploy the use of advanced data modeling and segmentation and the first to apply that data across multiple platforms of a campaign. In 2010, W&M was selected as the first ballot initiative firm to work with Nielsen and then Rentrak to deploy data-matched television ratings, allowing our campaigns to more efficiently and effectively target key voter segments. The firm also uses advanced data -targeting to deliver multi-tiered messages to the hard-to-reach and “cord-cutter” universes.

W&M utilizes cutting-edge artificial intelligence (AI) methods across nearly all components of its campaigns, including with the design and analysis of opinion research (qualitative and quantitative); development and targeting of all forms of paid media; organic social media content development and management; collateral development and refinement; and other areas.
