Protests are heating up over police brutality in the middle of a presidential election year. Can protests change election outcomes or the future of the parties? New research suggests that protests do leave their mark--and the Trump protest era has been quite active. Daniel Gillion finds that liberal protests help Democrats win elections, stimulating new campaign contributions, public support, and candidacies, and increasing their vote share. Michael Heaney finds that protests respond to the party of the president and can help the party out of power organize and voice its concerns. They both say we should not underestimate the power of street protests, even for conventional political outcomes.
