Grassroots groups canvas to register voters and fight voter suppression.

"The GOP’s 2022 Strategy: Voter Suppression or Bust. After failing to suppress enough Black votes to steal the 2020 election, Republicans are preparing for a heist the next time around." - The Nation

Fighting voter suppression requires helping eligible voter be prepared to cast their ballot in the face of stringent new Jim Crow style laws. Grassroots groups play a vital role in helping people in their community with voting related issues, but they face a logistical challenge.

How can grassroots groups with little money and staffing reach more voters in less time? How can they contact people who may not even be in the voter file? How can volunteers canvas better with real-time maps and upload their survey results immediately? How can all this be done by a grassroots group with few technical skills?

Use free, easy-to-use software. This blog explains how to create your own canvassing app for free with Google Sheets and Glide Apps software. There's also a free online tutorial and a link to get pro bono help to create your own app for voter registration canvassing campaigns.
