Brief 63: Impact of Negative Messages on Voter Turnout and Donations in the U.S.

This study was implemented during two local elections for county legislature during the 2010 general election in the U.S. Registered voters who had participated in the last 3 party primaries were randomly assigned into three groups—one to receive a positive message about the candidate, one to receive a negative message about the opponent, and one as control (which received no messaging). The messages were delivered by mail, and also provided the individual with the option of donating to the campaign.
