Current explanations of effective voter mobilization strategies maintain that turnout increases only when a potential voter is persuaded to participate through increased social connectedness. The connectedness explanation does not take into account, however, that registered voters, by registering, have already signaled their interest in voting. The theory presented in this article predicts that impersonal, noticeable messages can succeed in increasing the likelihood that a registered voter will turn out by reminding the recipient that Election Day is approaching. Text messaging is examined as an example of an impersonal, noticeable communication to potential voters. A nationwide field experiment (n = 8,053) in the 2006 election finds that text message reminders produce a statistically significant 3.0 percentage point increase in the likelihood of voting. While increasing social connectedness has been shown to positively affect voter turnout, the results of this study, in combination with empirical evidence from prior studies, suggest that connectedness is not a necessary condition for a successful mobilization campaign. For certain voters, a noticeable reminder is sufficient to drive them to the polls. 相似文献

ABSTRACTThis report examines accuracy and bias in national- and state-level preelection polls conducted during the 2016 U.S. general election cycle. Overall, national polls in 2016 were somewhat more accurate than in 2012, but statewide polls were less accurate. Patterns across the board suggest polls underestimated Republican support in the presidential, U.S. Senate and gubernatorial races. Nevertheless, these biases were generally statistically insignificant, suggesting significant bias in preelection polls was scarce in 2016. 相似文献
