Political conflict and its filtration into policy has many causal pathways, only a small dimension of which is captured by your scenario: a small minority significantly effected by policy X, and a large majority moderately effected by policy X, such that the minority has cause to exert a influence on policy X disproportionate to its membership. How would a crowd-sourced platform limit itself only to these cases? What would prevent it from becoming a forum for the pitting of distinct values or material interests against one another? Yet if you do pre-select campaigns in some way, what would distinguish the platform from existing mass-membership political campaign groups?
