Abstract: In addition to mobilizing supporters to vote, partisan campaigns
use get-out-the-vote tactics as a means to boost support for
their candidate. Although observational studies have attempted to
estimate the effects of grassroots campaigning on political
attitudes, they are unable to establish causality convincingly.
Because campaigns strategically target potential supporters,
comparing the attitudes of those whom campaigns contact to those
they do not may only reveal spurious and biased relationships. In
this paper I use a randomized field experiment to isolate the
influence of personally delivered campaign messages on candidate
support and attitude formation. I find that both door-to-door
canvassing and commercial phone bank calls can have strong
effects on voting preferences, but these tactics appear to have
only weak effects on the actual beliefs that subjects possess
about candidates and the degree to which those beliefs are
weighted in their candidate preference. Although previous field
experiments show that phone calls are less cost-effective at
boosting turnout than door-to-door canvassing, they may be
equally effective at increasing candidate support.
