A push poll is an interactive marketing technique, most commonly employed during political campaigning, in which an individual or organization attempts to manipulate or alter prospective voters' views under the guise of conducting an opinion poll. Large numbers of voters are contacted with little effort made to collect and analyze voters' response data. Instead, the push poll is a form of telemarketing-based propaganda and rumor mongering, masquerading as an opinion poll. Push polls may rely on innuendo, or information gleaned from opposition research on the political opponent of the interests behind the poll.
