This report shares the lessons learned from two 2019 statewide campaigns that were led by grassroots organizations working in coalition with broader policy and advocacy networks. Housing Justice for All and Green Light NY won significant changes for low-income renters and driver's licenses for undocumented immigrants, respectively. The campaigns challenged the model of traditional top-down advocacy by centering directly-impacted people from low-income communities of color in leadership and decisionmaking. Both campaigns also demonstrated that community power can be leveraged between grassroots electoral organizing and issue-based legislative campaigns. Finally, by centering member-led organizations from rural, suburban and urban communities, the campaigns demonstrated how progressive policy changes require long-term investment in groups that build people power across regional difference through shared mass mobilization strategies.
