Who do interest groups attract at the grassroots level

At grassroots level, they attract individuals who want to fight for a cause but do not have a platform to do so. They are about individuals joining and helping the cause and getting support, not about big governmental things or getting support from companies and sponsors and lobbyists or similar. Grassroots levels are designed for individuals who want to make a change.
