This document summarizes how St. Louis citizens organized to pass a transit tax measure in 2010 after previous failures. It describes how the Citizens for Modern Transit group organized an education campaign to build support, focusing on champions, coalition building, research, messaging, and get-out-the-vote efforts. Their campaign involved radio, web, and grassroots activities promoting transit's benefits. On the April 2010 ballot, the measure passed 63% to 37%, marking a dramatic increase in support over previous attempts, showing how citizen involvement can impact transit referendums.
