Check out Sister District’s new Downballot Toolkit, including resources to combat roll-off and motivate voters to vote all the way down the ballot. The toolkit contains key research findings, messaging guidance, and tested, effective content available for download.
Click to learn more about which voters roll off their ballots after voting at the top of the ticket, and the common barriers they face. See our top-performing messages and understand what makes them effective. We provide sample ads, including a video, that can be downloaded and shared.

All research studies and experiments are carried out by the Sister District Action Network (SDAN), the 501(c)(4) non-profit affiliate of Sister District.
Under the direction of Dr. Gaby Goldstein and Jillian Evans, the SDAN team specializes in political research and civic engagement, focusing on things like voter behavior, volunteer engagement, outreach methods, and messaging.
We are excited and honored to work alongside researchers at such well respected institutions as the Voter Participation Center, the Mississippi NAACP, Virginia Tech University, and the University of Michigan.
In addition to evaluating the efficacy of different engagement tactics and communication methods, the SDAN team also looks into trends within:
Voter Behavior
Voter Registration, Voter Turnout, Voter Demographics
Voter, Volunteer, Fundraising Messaging
Get Out The Vote (GOTV) Messaging, Persuasion Messaging, Contact Timeline, “Friendraising”
Volunteer & Field Activities Research
Postcarding, Phonbanking, Textbanking/ Text Messaging, Political Canvassing

Bottom line: Traditionally, methods using live conversation (e.g., canvassing and phonebanking) are more effective than other methods of voter outreach.
Bottom line: Canvassing has traditionally been known as the most effective form of voter contact because of the opportunity for face-to-face, two-way communication.
Bottom line: If canvassing is not an option, phonebanking has traditionally been the next best thing.
Bottom line: The effectiveness of textbanking needs more research. There’s evidence that text messaging has small effects on voter turnout and voter registration.
Bottom line: The effectiveness of handwritten communications like postcarding and letter writing needs more research. There’s evidence that both have small effects on voter turnout and that postcarding has a small effect on voter registration.
Bottom Line: Direct contact with volunteers results in more participation.
Bottom line: Relational organizing is the most impactful tactic that individuals can use to influence elections.
Bottom line: Social pressure is highly effective and social pressure mail has been shown to be more effective than regular direct mail.
SDAN’s white papers are meant to provide enough detail about our studies to allow others to completely understand our findings and replicate our methods. These white papers provide more rationale behind the studies, as well as more detail about methods and analyses employed, compared to our blogs and short reports. They are perfect for fellow scientists and number crunchers, as well as anyone who is curious about learning more about what went into a particular study. White papers are published as they are available.
