Since 2014, a number of protests in the United States have deliberately blocked limited-access highways to increase protest visibility and to connect to long-standing political meanings of transportation infrastructure. In response, in 2017 seventeen states introduced twenty-one pieces of legislation aimed at stopping such protests, whether through increasing criminal penalties, creating new violations, or indemnifying drivers who accidentally hit protestors. Although only two of these bills passed into law, they are still of interest for what they demonstrate about state-level legislative responses to protest. This research answers the question via logistic regression of why some state legislators supported these bills by sponsoring or cosponsoring them and others did not. In the end, the political party of the legislator was the most important factor, but other geographic and political variables mattered as well, including the conservatism of voters and the whiteness of the district population.

流动性、抗议和立法反弹：2017 年美国反抗议立法的州级赞助

自 2014 年以来，美国的一些抗议活动故意封锁了限制进入的高速公路，以提高抗议的知名度，并与交通基础设施的长期政治意义联系起来。作为回应，17 个州在 2017 年推出了 21 项旨在阻止此类抗议的立法，无论是通过增加刑事处罚、创造新的违规行为，还是赔偿不小心撞到抗议者的司机。尽管这些法案中只有两项通过成为法律，但它们仍然对州级立法对抗议的反应所展示的内容感兴趣。这项研究通过逻辑回归回答了为什么一些州立法者通过赞助或共同赞助来支持这些法案而其他人没有的问题。到底，
