Mobilizing Peripheral Partisan Voters: A Field Experimental Analysis From Three California Congressional Election Campaigns

Since the early 2000s, an array of experimental research has demonstrated that face-to-face canvassing is the most effective form of get-out-the-vote campaigning. Recent scholarship, however, suggests that text messaging can also have powerful mobilization effects. Can the effects of text messaging match those of canvassing? We present a field experiment gauging the effects of text messaging, canvassing, mail, and phone calls among medium propensity evangelical Christian voters in three California battleground congressional districts for the 2018 midterm election. The results show significant turnout effects associated with texting as well as any form of outreach followed by a late-October text message. This challenges the widely held notion that personalized contacting is required to get voters to the polls; rather, we find that peripheral voters—often targeted by campaigns for mobilization—may be receptive to anonymous but timely outreach.
