The Poor People’s Campaign (PPC) of 1968 was focused on highlighting, and ultimately reducing, poverty in the United States. As part of the campaign, protestors from across the country were transported to Washington, D.C. in 6 separate bus caravans, each of which made stops en route to rest, recruit, and hold non-violent protests. Using data from 1960–1970, we estimate the effects of these protests on congressional election outcomes. In the South, we find that PPC protests led to reductions in Democratic vote share and turnout, while in the West they may have benefited Democratic candidates at the expense of their Republican rivals.

民权抗议和选举结果：探索穷人运动的影响


1968 年的穷人运动 （PPC） 的重点是突出并最终减少美国的贫困。作为活动的一部分，来自全国各地的抗议者被 6 辆独立的巴士大篷车运送到华盛顿特区，每辆巴士大篷车都在途中停下来休息、招募和举行非暴力抗议活动。使用 1960 年至 1970 年的数据，我们估计了这些抗议活动对国会选举结果的影响。在南方，我们发现 PPC 抗议导致民主党的选票份额和投票率下降，而在西部，它们可能以牺牲共和党对手为代价，使民主党候选人受益。
